Surveillance Satellite

Overview

This OXP adds satellites to the main planet, plus any secondary planets that may be available through Additional Planets.

Ideas with a revolutionary potential sometimes remain underestimated or just unnoticed!

This is the case for the Satellites OXP (author – Rorschachhamster). Seemingly just a nice exercise in coding and just one more OXP in the Ambience category.

But, it is a jolly hard task to simulate true orbital dynamics in Oolite:

In the real world, the calculation of orbital dynamics is based on the integration of acceleration vectors and on the energy conservation law. If you have no acceleration produced by a propulsion engine, your total energy (sum of kinetic and potential energy) would have a constant value. So on an elliptic orbit you’ll trade velocity for altitude and vice versa.

In Oolite we have no gravity nor energy. Acceleration is limited to propulsion acceleration/deceleration parameter thrust and this is not a vector value – it is just the rate of change of ship speed. So we need some trick to simulate true orbital dynamics – calculating the ship's position for the next frame and placing the ship directly into it.

Unfortunately JavaScript is not a suitable instrument for smooth dynamic simulations! It generates only 4 fps, so you’ll see the jerky sequence of frames instead of a decent illusion of smooth movement.

Bad idea. Forget it.

Satellites OXP uses a more elegant approach, based on AI behavior. It generates a realistically looking pattern of circular movement around a planet without sophisticated mathematics.

Satellite Types

There are 4 different types of satellite that can be added to a system.

Surveillance Satellites

These satellites are designed to map and scan planetary regions, down to a very fine detail level.

COM and COMLR Satellites

These satellites aid and facilitate intra- and inter-planetary communications.

Satellite Telescope

These satellites are designed to scan deep space for anomalies (like Thargoid invasion craft or rogue comets and asteroids).

Version History

1.11

  • Added normal and specular maps and gloss values to all satellites.
  • Moved (very limited) text to descriptions.plist for easier localisation.
  • Fixed issue where Library Config settings were not being added correctly.

1.10

  • Fixed small bug that was preventing 2 satellite types from having their beacons hidden on secondary planets.

1.09

  • Fixed bugs with Library interface.

1.08

  • Destroyed satellites will stay destroyed in the current system until you leave.
  • Small bugfix in the save game routine.

1.07

  • Small bugfix in the new populator.

1.06

  • Reworked populator methods to use new functions, and to make the number and types of satellites the same in each system.
  • Added satellites to any extra planets in the system.
  • Added Library config options to turn off beacons and control the number of satellites spawned.

1.05

  • Added check if mainplanet is existent, in case of nova system... and corrected versions in scripts.

1.04

  • Added AI-code by Dr.Tripsa, that will let spy-sats work as police, and reduced texture size with Optipng thanks to a tip from Shipbuilder. Cleaned up the shipdata.plist, as well.

1.03

  • ...and if you change the texture names, you should change the names in the model.dats as well... and I should probably test before I release a "fixed" version. Sorry.

1.02

  • --and deleted a paste and copy error...

1.01

  • Changed the roles, models , textures etc. to more unique names to avoid compatability issues, thanks again to Eric Walch. Corrected the demoship.plist, so that all 4 satellites can be seen...

1.0

  • Original release.
