TRIMBLE R8 GNSS SYSTEM
1 The availability of L2C and the L5 signal is dependent on the US Government.
2 Accuracy and reliability may be subject to anomalies such as multipath, obstructions, satellite geometry,and atmospheric conditions. Always follow recommended survey practices.
3 Depends on WAAS/EGNOS system performance.
4 May be affected by atmospheric conditions, signal multipath, and satellite geometry. Initialization reliability is continuously monitored to ensure highest quality.
5 Receiver will operate normally to –40 °C, Bluetooth module and internal batteries are rated to –20 °C.
6 Varies with terrain and operating conditions.
7 Bluetooth and GSM type approvals are country specific. Contact your local Trimble authorized distribution partner for more information.
