According to the Update 11.2.2021 (Alpha 353) patch notes and what others have said and the wiki, The transponder is supposed to have some fields
It looks like few if any of these work. Flying around in the safe zone, that field always shows 0. stationsAllowed also doen't work. The wiki list other fields also:
rangetransponderActive - On/off: 0 - 1
transponderOwner - Owner of transponder/ship. - Filled at creation: string
transponderShipName - Name of ship that transponder is tied to. - Filled at creation: string
insideSafezoneIs - the transponder inside a safe zone?: 0 - 1
playerDamage - Can this ship currently be damaged by players?: 0 - 1
shipDamage - Can this ship currently be damaged by other ships?: 0 - 1
collisionDamage - Can this ship currently be damaged by collisions?: 0 - 1
stationsAllowed - Can a new station be constructed in the current area?: 0 - 1
Looking at my transponder on my starter ship, Both those string fields just have 0. The only field that changes to anything else is the first one which changes to 1 when the transponder is on. The rest of the fields are not effected by the transponder being on or off. The on/off state shouldn't matter anyway for the rest of the fields.
Transponders
- Added device fields that inform the current area rules (insideSafeZone, playerDamage, shipDamage, collisionDamage, stationsAllowed)
- Provides 0 if the rule is false, and 1 if the rule is true
