Investigation of Supercruise Velocity as a Gravitational Detection Mechanism in Elite Dangerous

Abstract

This investigation examined whether a spacecraft’s velocity during supercruise can function as an indirect sensor for detecting gravitational influences that may not otherwise be apparent through conventional navigation or targeting systems.

The investigation had three primary objectives: (1) determine whether supercruise velocity can be used as an additional ship sensor for detecting gravitational anomalies; (2) characterize the limits and behavior of this potential sensor; and (3) determine whether the technique could assist in locating known or suspected hidden astronomical objects, including the Pareco comet.

Initial experiments indicated that a ship’s velocity can change as it approaches a gravitationally influential object even when that object is not explicitly targeted. A neutral-velocity bearing could also be used to approximate a direction roughly perpendicular to the gravitational influence. These observations support the existence of a measurable relationship between ship velocity and nearby gravitational influences.

However, subsequent testing at Pareco demonstrated a significant practical limitation. Although velocity behavior could indicate the presence of a gravitational anomaly, the game applies positional corrections and large-scale supercruise movement near objects and stations, making it extremely difficult to use velocity alone to determine an exact position or deliberately exit supercruise at the center of a suspected hidden object.

The investigation also produced a separate observation concerning the journal representation of comets. Historical journal entries represented comets using BodyType: “SmallBody”, whereas testing of the current game version indicated that comets are now represented as BodyType: “Star”. This change potentially complicates automated journal-based searches for anomalous or hidden cometary objects.

The investigation therefore establishes that supercruise velocity can provide information about nearby gravitational influences, but does not establish a practical method for independently locating and entering hidden cometary objects. Signal Sources are identified as a potentially important avenue for future investigation.

1. Introduction

The objective of this project was to investigate whether supercruise flight behavior could provide information about gravitational influences beyond what is normally exposed through the game’s navigation interface.

The underlying concept was that a spacecraft’s velocity is affected by its position relative to a gravitational body. If these changes could be measured independently of the normal targeting system, ship velocity could potentially serve as an additional, indirect sensor.

The investigation was motivated in part by attempts to locate unusual or difficult-to-access astronomical objects, including the Pareco comet and Halley’s Comet. The project therefore sought not only to establish whether the phenomenon existed, but also to determine whether it could be used practically to locate otherwise hidden objects.

2. Research Objectives

The investigation defined three primary objectives:

• Determine whether supercruise velocity can function as an additional ship sensor.
• Determine the operational limits of this potential sensor.
• Test the technique against known or suspected hidden objects, particularly the Pareco comet and Halley’s Comet.

3. Experimental Method

3.1 Basic Detection Procedure

The proposed detection procedure consisted of entering supercruise within a stellar system and reducing the spacecraft to its lowest controllable speed.

The ship was then oriented away from a stellar body without targeting it. After establishing a relatively stable or increasing velocity, the ship was rotated approximately 180 degrees to point directly toward the body.

The observed behavior was that the spacecraft would continue losing velocity after the turn, including while pointed toward the stellar body despite that body not being selected as the target.

When the ship was rotated away from the body again, the turn itself produced a temporary velocity loss, after which the ship began gaining velocity once oriented away from the gravitational influence.

This procedure was intended to distinguish velocity changes associated with orientation relative to a gravitational source from ordinary changes caused by the act of turning.

3.2 Control Environment

Initial experiments were planned in Col 285 Sector TN-D a28-1, a system containing a single stellar body described as a T-class star/brown dwarf.

The selection of a single-body system was intended to minimize confounding variables arising from multiple gravitational sources. This experimental arrangement was useful because any systematic velocity behavior could more readily be associated with the known stellar body rather than an unidentified secondary source.

3.3 Neutral-Velocity Bearing

An additional observation was that it was possible to approximately identify a bearing at which the spacecraft neither gained nor lost velocity.

This neutral-speed bearing was interpreted as approximately 90 degrees from the gravitational source. The observation was not treated as an exact angular measurement because the spacecraft eventually began accelerating as it moved outside the gravitational sphere of influence.

This suggests that velocity behavior may provide not merely a binary indication of the presence of gravity, but potentially directional information about the location of a gravitational source.

4. Initial Findings

The initial observations supported the existence of a measurable relationship between spacecraft velocity and gravitational influence.

The important feature was that the effect did not appear to require the gravitational body to be explicitly targeted. This raised the possibility that ship velocity could function as an independent source of navigational information.

The potential technique was therefore conceptually different from conventional navigation targeting: conventional navigation identifies and targets a known object, whereas the proposed velocity sensor detects the physical effect of an object on the spacecraft. The latter could potentially reveal the presence or direction of an object before it is directly identified.

5. Pareco Investigation

5.1 Objective

The Pareco system was selected as a practical test environment because of the known difficulty associated with reaching its comet.

The objective was to determine whether velocity changes could be used to locate the comet’s gravitational influence and ultimately permit the spacecraft to exit supercruise at or near the object’s location.

5.2 Detection of the Gravitational Influence

Testing at Pareco produced an important positive result.

The experimenter reported that the ship’s speed could indeed be used to detect a gravitational anomaly. This remained true even when the suspected object was not selected as the ship’s target. As the spacecraft approached the target region, its velocity decreased.

This constitutes the principal positive result of the investigation: supercruise velocity can provide information about a nearby gravitational influence independently of explicit target selection.

However, the observation did not by itself provide a sufficiently precise method for locating the center of the gravitational influence.

5.3 Positional Instability Near the Target

The investigation encountered a major problem when attempting to approach the precise center of the anomaly.

At extremely close range, the game appeared to apply a positional or movement correction. The experimenter reported that, even with the throttle at zero, the spacecraft could be moved forward toward a nearby station.

Testing between two nearby stations produced an especially notable effect: as the ship approached one station while moving away from another, the relative distance appeared to change instantaneously, as though the ship had been displaced a substantial distance.

The experimenter further reported that adding even a small amount of throttle could result in a very large positional displacement before the game resumed the slow approach behavior at extremely close range.

This behavior made it difficult to determine an exact center point using velocity alone.

6. Attempted Supercruise Exit

The next stage of the experiment attempted to predict the appropriate time and distance at which to exit supercruise in order to arrive at the suspected object.

No successful independent exit onto the target was achieved.

A recurring problem was that the test location was within or near another station’s sphere of influence. Signal Sources were observed to spawn outside stations or at stations, but not within the station’s sphere of influence.

This produced an important limitation: even if the gravitational anomaly could be detected, the surrounding gravitational and navigational environment could prevent the spacecraft from approaching the suspected center sufficiently accurately to perform a controlled supercruise exit.

7. Signal Sources as a Potential Access Mechanism

The difficulty of independently entering the suspected comet location led to a secondary hypothesis.

Other players had reportedly succeeded in dropping into the Pareco comet, while the present experiment was unable to reproduce the result. This raised the possibility that access might depend on a specific game-generated Signal Source rather than simply navigating to the object’s gravitational location manually.

The investigation therefore proposed that future research should examine the spawn criteria and positioning of Signal Sources.

This remains a hypothesis rather than an established mechanism.

8. Journal Representation of Comets

A separate finding emerged during examination of player journals.

Historically, comets were represented in journal data using BodyType: “SmallBody”.

The investigation noted that comets in the current live version of the game are instead represented as BodyType: “Star”.

The associated body-name information was also reported to have been removed, requiring identification through BodyID. The change was identified by comparing reachable comets in legacy and live versions of the game.

This is significant for journal-based investigations because searches specifically looking for SmallBody entries may fail to identify cometary objects in current game data.

The discovery also provides a possible explanation for why automated journal analysis may not immediately identify a modern comet as anomalous: an object that historically had an unusual SmallBody classification may now appear simply as a Star.

The reason for this change was not established by the investigation and should not be inferred from the available evidence.

9. Pareco Comet Geometry

Further discussion established that the Pareco comet is located extremely close to the sphere of influence of a station.

The reported geometry places the station’s sphere of influence at approximately 1,000 km and the comet’s approximately 50 km sphere of influence at roughly 1,030 km from the station. An approach along the plane of the comet’s orbit was proposed as a means of reaching the object while maintaining approximately 1,000 km separation from the station.

This geometry provides a plausible explanation for at least part of the practical difficulty encountered during the experiment: the comet’s local region overlaps or nearly overlaps the station’s navigational influence.

10. Legacy and Live-Version Differences

The investigation also clarified an important distinction between the legacy and live versions of the game.

Discussion initially concerned whether an earlier identification method could still be used to reach the comet. The final exchange established that the ID64 method still works in the legacy version, while the current live representation differs.

Consequently, experimental results involving comet identification or access should specify the game version used. Results from legacy Elite Dangerous cannot necessarily be assumed to apply to the current live version.

11. Discussion

11.1 Positive Result: Velocity as a Gravitational Sensor

The experiments support the conclusion that spacecraft velocity contains information about nearby gravitational influences.

The effect can apparently be detected without explicitly targeting the associated object. This makes velocity behavior potentially useful as a supplementary sensor when investigating an unknown or difficult-to-target object.

The neutral-speed bearing observation further suggests that the effect can provide directional information, although the accuracy of such a bearing was not quantified.

11.2 Negative Result: Practical Localization

The experiment did not establish that velocity alone provides a practical method for precisely locating and entering a hidden object.

At very close range, positional behavior became difficult to control. The presence of nearby stations introduced additional spheres of influence and apparent positional corrections. These effects prevented reliable convergence on the suspected center.

Therefore, the experiment demonstrates detectability, but not practical independent localization.

12. Limitations

• Quantitative measurements: The investigation primarily recorded qualitative observations of acceleration and deceleration. No complete dataset of distance, velocity, acceleration, heading, time, gravitational source, or angular offset was recorded.
• Multiple gravitational influences: The Pareco experiment was complicated by nearby stations and their spheres of influence, making Pareco unsuitable as a simple isolated test environment.
• Game movement corrections: The observed positional jumps near objects introduce an additional source of uncertainty and can make precise localization difficult.
• Unresolved Signal Source mechanism: The possibility that Signal Sources provide a mechanism for reaching otherwise inaccessible locations remains untested within this investigation.
• Version dependence: The representation of comets in player journals has changed between game versions. Journal-analysis methods must therefore account for version-specific data structures.

13. Conclusions

• Supercruise velocity can be used to detect gravitational influences.
• The effect can occur without the gravitational source being explicitly targeted.
• Velocity behavior may provide directional information about a gravitational source.
• The technique becomes unreliable as a precision navigation method at extremely close range because of game movement and positional behavior.
• The Pareco environment is particularly difficult to use for manual localization because of nearby station spheres of influence.
• The investigation did not establish a reliable method for independently entering the Pareco comet using velocity measurements alone.
• Historical journal data represented comets as SmallBody, while the current live game represents them as Star, requiring different approaches to journal-based comet searches.
• Signal Sources represent a potentially important avenue for future research into how players can reach otherwise difficult-to-access locations.

14. Recommended Follow-Up Research

The most direct continuation of this work would be a dedicated investigation of Signal Source generation and placement.

• Under what conditions does a Signal Source spawn?
• How is its position determined?
• Can a Signal Source spawn at or near an otherwise inaccessible astronomical object?
• Does the Signal Source inherit the location of an underlying object?
• Can the existence of a Signal Source reveal an otherwise undiscoverable gravitational source?
• Are Signal Sources associated with specific mission states, navigation states, or player actions?
• Do Signal Sources appear at consistent distances from stations, planets, stars, or other objects?
• Can clusters or patterns of Signal Sources be used to infer the presence of an underlying object?
• Do legacy and live versions generate or position these signals differently?
• Can journal events establish a relationship between a Signal Source and an object that is not otherwise present in the normal navigation data?

A controlled Signal Source study could potentially build on the gravitational-sensor work by combining velocity measurements, signal-source coordinates, supercruise exits, journal events, and known astronomical-body positions.

This would shift the investigation from the question “Can the hidden object be detected?” toward the more useful question: “What game mechanism provides the player with a navigable route to an object that cannot otherwise be directly targeted?”

Overall Finding

The investigation identified a genuine and potentially useful relationship between supercruise velocity and gravitational influence, but the available experiments did not turn that relationship into a reliable method for locating or entering hidden astronomical objects. The most significant remaining avenue is therefore not further refinement of velocity-based navigation alone, but investigation of the Signal Source system and its relationship to otherwise inaccessible locations.
