| CHC X90G Network RTK GPS Receiver |
X90G GPRS surveying system is an All-in-one cable-free dual- frequency RTK system. It is a
Network Communication version of CMC X90, which uses the RTK solutions from the CHC LandStar software and provides high-accuracy, RTK GPS positioning for wider areas.
|
| X90G GPRS surveying system can be used in two models:- |
VRS Model: If the fixed VRS (Virtual Reference Station) network is available, X90G GPRS surveying system is able to do the normal RTK work without setting up a base station.
Network RTK: If the VRS network is not available, the X90G can also be used in the GPRS/CDMA Network to get the RTK solution, which is called Network RTK. A base station and a server on-line are desired for this. |
| GPRS/GMS |
| Build in GPRS/CDMA makes a radio-free surveying environment: |
- Low interference
- Fast dialing on-line and high stability
- Low power consumption
|
| L1/L2 Antenna |
| Internal GPS antenna minimize the multipath affection, and proves the low elevation tracking technology and the zero phase centre error advantages. It is designed to receive L1 C/A Code and L1/L2 Full Cycle Carrier. |
| Bluetooth |
| Integrating the Bluetooth technology, cable-free communication between receiver and controller is available. |
- Long controlling distance
- Flexible switching between receivers
- High stability of communication
