To calculate your position, any system must measure the distance to four reference transmitters. A single receiver can make one measurement every two ticks. Thanks to improved measurement of the reference transmitter positions and the new system allowing a better choice of reference set, the position (and calculated derivatives) are now much more accurate compared to V1/
Base versions output position to the X, Y & Z fields:
-
Mono, requires one receiver, base update rate: 3 ticks
- accurate in any frame with constant acceleration
- Single basic chip
- The single receiver polls each of the four selected transmitters, then the system uses a quadratic prediction system and the previous 12 measurements to estimate what the latest measurements would have been if all taken in the same tick
-
Duo, requires two receivers, base update rate: 3 ticks
- accurate in any frame with constant acceleration, quickly reacting to changes
- Single basic chip
- The middle-man between Mono & Quad, using similar prediction to mono, except measurements can be taken twice as fast, so the previous 12 measurements used for prediction are much more up-to date, allowing for faster reaction to changing acceleration
-
Quad, requires four receivers, base update rate: 2 ticks
- as accurate as can be, always
- Single basic chip
- Able to measure to all four reference transmitters simultaneously ever two ticks
