The GPS2 is a high-accuracy dual frequency differential GNSS (GPS+Glonass) receiver, capable of measuring position at up to 2cm accuracy whilst mobile. The GNSS solution is output over serial in a format suitable for interoperating with other Race Technology devices, and over CAN to allow direct customer access to the data.
The GPS2 is available as either a standalone version without RTK corrections (GPS2), or as a full RTK solution which requires corrections from a data source (GPS2 RTK).
The GPS2 RTK tracks L1+L2 GPS+GLONASS constellations, and operates at 2-3cm positional accuracy when receiving differential corrections.
Corrections can be received either via. radio modem, or from an NTRIP caster service via. GSM. The choice of correction is selected using the configuration software and interfacing the required hardware (SIM card and NTRIP subscription, or radio modem and base station).
The GPS2 tracks L1 GPS+GLONASS constellations, and operates at 1-2m position accuracy under typical test track conditions.
The GPS2 can be upgraded to a GPS2 RTK, it will be necessary to return the unit to the factory if this is required.
The GPS2 can be used as a standalone high-precision GPS receiver, outputting position, speed, heading and gradient over CAN at up to 20Hz output rate.
However, the main intended application of the GPS2 is as an upgrade to the Race Technology SPEEDBOX-INS, and the Race Technology CATS complete automotive testing system.
Using the GPS2 with the SPEEDBOX-INS or CATS system gives broadly similar performance to the native SPEEDBOX-INS, but with the added benefit of using GLONASS in addition to GPS, which can be useful at some test circuits.
Using the GPS2 RTK with the SPEEDBOX-INS or CATS gives all the benefit of the proven speed and attitude accuracy of the SPEEDBOX-INS, with the addition of positional accuracy upgraded from the 1m level to the 2-3cm level. This brings many more applications within the remit of the SPEEDBOX-INS / CATS system, including:
- Driving robot input
- Lane deviation testing
- Target tracking
- Driver assistance development and end-of-line testing
- Driverless vehicle research and development
