system
The system contains rover and reference-station. Correction data is sent with a licence-free radiomodem between rover and reference. There are no costs for receiving gps-signals or radio. The receivers are high precission single frequency gps types.
hardware and software
How to get started? For a test drive you need only 1x Development-Kit + 1x REC-NN + 1x Antenna Kit. If you take the REC-2RF or REC-2RF2BT or REC-2BT boards you will have a fully operational system as it is used in many surveying systems.
It's also possible to get a full software implementation from us... please ask.
performance
The accuracy of the measurement is around 10mm for longitude and latitude and 15mm for height. The radiomodems works up to 1km. After the rover and base are switched on it will take 2 minutes until the system is ready for init. Initialization will take 15 seconds at a known position and usually 2-7minutes on the fly. The values depends from the satellites constellation.
