Space Traffic Control.

Control Levels

Level 1 - Starports (essentialy local towers) Level 2 - Orbital Control ( handles local Traffic and approach control) Level 3 - Space lanes Level 4 - Space based IFR Zone... Level 5 - Deep space. (i.e out of range of STC radio relays)

Orbital Control (level 2)

== Lane managment (Level 3)

Flght Rules Zones (level 4)

Off limits space... Restricted Airspace (for example Demios, Europa)

Space Patrol/ Star Corps

As well as other 'civil' vessels, millatry(Star Corps) and police vessels (Space Patrol) will be encountered

Star Corps/Space Patrol use the call sign VIPR(Victor India Papa Romeo) with VIPR42 being used exclusively by Space Patrol.

Space Patrol interceptors work in pairs.

Firing on, or acting suspciously towards to Space Patrol or Star Corps vessels is not advised, by doing so you are classifed as 'hostile' or pirate and actively hunted.

In addition to 'security' Space Patrol also run the rescue service and have been known to escort 'troubled' vessels in an some landing sites/bases.

• So VIPR42 is essentaly the call sign for the Space Patrol

<mirwin> True I think we coould actions classify player ships. Act like pirate treat like pirate. Blown out of sky. Little crew guys for space patrol to pick

Whilst most cival vessels carry IFF(Interogate Friend or Foe) equipment, this isn't foolproof.

One thing all 'civil' vessels have to know if the Star Corps intercept procedure.

If intercepted co-operate, Space Patrol do NOT under normal conditons open fire first. The intercept procedure is a follows.

To intercept, they Space Patrol will overfly on the port and starboard sides of a vessel and execute a roll while doing so. While executing the role the Vipers will issue a 'CEPT <vessel call sign>' message on all channels.

• An intercepted vessel is REQUIRED to acknowledge CEPT's by repeating the call back to the VIPR's over the radio, and/or making a rocking motion (should radio coms be difficult).

• If this is ignored - the overflight is repeated twice again with CEPT calls.

• If a CEPT is ignored three times in succession, then VIPR's can shoot to disable

but cannot shoot to kill.

If during an intercept, VIPR's receive hostile fire, use of return fire is authorised. Firing weapons is NOT acknowledgement.

The aim being to stop trouble developing

• If fired upon VIPR can immediately return fire?

Assuming Hostile ifre that is...

Sparks or debries falling off doesn't count

• Star Corps don't shoot without questions
• Which is why there is an intercept procedure
• Star Corp picks up prisoners

• Of course if ships ignore intercept proecdure Star Corps objective is shoot to disable
• Known troublemakers or obvious risks will be blasted.

<mirwin> <ShakespeareFan00> Civil vessels tend to have IFF <ShakespeareFan00> Absence of IFOF is a no-go item at launch <ShakespeareFan00> Sorry just thinking in terms of procedure here... <mirwin> "IFF Identify Friend or Foe <ShakespeareFan00> *friend <mirwin> got it <ShakespeareFan00> legitmate vessles would not have good reasons to avoid having it <mirwin> IFF integogate friend or foe <ShakespeareFan00> OK <ShakespeareFan00>

Specialist codes

These are some 'special' codes you may hear in trafic control messages.

All these are sounded phonetically, for example...

Victor-India-Papa-Romeo please state intention.

Victor-Alpha-Delta,Romeo please identify IMMEDIATELY

• V,A,D,R - Unidentified rouge ship
• V,I,P,R - Space Crops military vessel - (You don't mess with these!)
• B,O,M,I - Presidential 'Yacht'.
• S.T.A.R - Diplomatic Vessel

Indications ussaly sounded phonetically:

• EVA - I have persons active outside vessel
• LAME - (to tower) I have partial loss of manouvrability
• DEAD - (to tower) I have TOTAL loss of manovrability
• CHOKE - (to tower) I have loss of life support.

Call Signs

In respect of Sol system call signs for spacecraft are centrally allocated in respect of civil vessels. Millatry vessels are ussaly Star Corps...

Vehicle classes: Sounded phonetically,

• V,I,P,R : Used for ALL military and police vehicles (Additonals chacters are assigned by

the Space Corps as needed for indvidiaul vessels)

• S,T,R - Heavy freighter
• F,T,R - Freighter
• T,D,R - Trader
• P,A,S - Passenger Vessel, Large
• P,E,R - Passanger vessel, Small
• P,L,X - Pleasure craft
• O,O,K (Abrvetaion of Coocon)- Cyrogenic suspension vessel, frequently unmanned.

Games Inspiring some Features

• Asteroids
• Elite
• Lunar Lander
• Nomad
• Xpilot
• virtual airpor (never published, out of busines, mirwih has rights to code and art)

The way we hope this to eventually work is we have a net of little space games that interact in a MUD (multi-user dungeon). We will possibly interface with JFreerails via a spaceport. There is a loading module with some educational and fun mass distribtion. Then comes Terran Takeoff (horizontal or vertical), both talking to STC, the asteroids/Xpilot, then talk with Lunar STC, lunar landing, mission is now complete.

We will have a lunar rover gamelet. JFreerails is already playable and I think easily added to for an interface to the spaceport. Subgames in cisLunarFreighter could be broken out as loading game, lunar lander take off or horizontal orbiter, both those talking to STC, then asteroids/xpilot, then talk to STC, lunar lander, mission complete, see what I mean by "little space games"

Base/Vehicle Operational Standards

	<mirwin>	have any ideas on how a pirate base would operate ...they would not use STC?
	<ShakespeareFan00>	mirwin: Well, a priate base would try to operate within STC as far as they could
	<ShakespeareFan00>	but they would have thier own procedures...
	<mirwin>	good point flyby's maybe necessary to identify or follow pirate ship in
	<ShakespeareFan00>	STC has a special code VADR for unidentifed vessels
	<ShakespeareFan00>	VADR vessels behaving in a hostile manner and that don't respond to cept messages are liable to be disabled...
	<ShakespeareFan00>	mirwin: However operating a base outside STC rules is a serious matter...
	<ShakespeareFan00>	Star Corps have been known to be 'unpleasent' with rouge operators...
	<mirwin>	hmm maybe a rover trip ground inspection of some kind
	<ShakespeareFan00>	Thats or a flyover...
	<ShakespeareFan00>	All 'legit' bases have to confirm to STC spec
	<ShakespeareFan00>	Like having certain mimumum equipment standards, radar etc
	<ShakespeareFan00>	Pirate bases of course might not have the same standard of equipment...
	<mirwin>	there was an asteroid style game with gravity and bunkers ... good model for simple flyover prototype LSG
	<ShakespeareFan00>	'legit' cival bases also have to register...
	<ShakespeareFan00>	the Sol Registry containing at presnt abvout 30 known bases...
	<ShakespeareFan00>	Star Corps keeps it's own list of milatyr facilities
	<mirwin>	ah good - players pick site and establish bases and facilities -- ties to Lunar Boom Town
	<ShakespeareFan00>	(sometimes these are shared with 'cival' ones)
	<ShakespeareFan00>	Or buy into common ones...
	<ShakespeareFan00>	The STC is in effect a bit like the FAA
	<ShakespeareFan00>	but in some areas it has more powers , and some less
	<ShakespeareFan00>	For example the STC can ground usafe vessels
	<ShakespeareFan00>	I don't think the FAA can canit?
	<mirwin>	or buy abandoned miliatary! Imagine a flyover that turned from easy picking to lets get the hell out of here if we can!
	<mirwin>	oh yes FAA shuts down unsafe in seconds
	<ShakespeareFan00>	mirwin: The millatry tends to hang onto it's fcailites...
	<mirwin>	if they can spot it in paperwork and inspections
	<ShakespeareFan00>	STC also inspect facilites as well as vehicles...
	<mirwin>	true - be rare abandond secret bases ...CIA types
	<ShakespeareFan00>	The Star Corps knows about some of these... but won't tell ;-)

Implementation Details

We could have a percentage reportig damage. Certain probably of blowing up when damaged. survivers to pick up after shp blows but player loses ship.

Friendly fire incidents occur when Star Patrol shoots civilian
