Home » New Internal Radio Solutions for the Trimble R8 GPS System Deliver Wireless Convenience 7.19.04
Trimble introduced two new wireless communications options for the L2C signal-ready Trimble R8 GPS system-an internal transmit/receive 450 MHz radio module and an internal GSM mobile phone module. Both options enable the Trimble R8 GPS receiver to function as a high-precision surveying system without the inconvenience of cables.
High-precision RTK GPS surveying requires a radio data link between a base station and survey rover. With the new radio transmit option, users no longer need an external radio for the base station, providing increased convenience and cost-savings. In addition, the internal transmitter eliminates the need for complex cable connections between the GPS receiver and radio, reducing setup and training which translates to more time surveying. The internal base radio also adds flexibility to the surveyor's workflow. The base station and rover are completely interchangeable and time spent searching for a base location with best radio coverage can be eliminated by using a radio repeater within 3-5 kilometers.
