IGTS ( INS GPRS Telemetry System)
GPRS (General Packet Ratio Service) - uses GSM technology for data transmission. The main advantage of GPRS is in economics - you only pay for the data transmitted, not for connection time. Therefore, because the amount of data in the case of RTK differential corrections is small, GPRS is inexpensive. In addition, when comparing to the UHF telemetry system, GPRS has no range limitation.
In many cases, when working in the field, we need to utilize one mobile reference station and many rovers. The mobile reference station may not have the opportunity to connect to a PC and internet. Our IGTS system provides a solution in such a working environment.
GPS differential corrections can be handled in any format (RTCM, DBEN, CMR, CMR+), depending on the brand of GPS hardware and its requirements. However, both the reference station and the rover must be compatible in that respect. For example, if the reference station generates corrections in the DBEN format, the rover must be able to work with them.
The reference station segment of IGTS can be utilized in two different scenarios:
- by use of IGTS hardware connected directly to the mobile reference station to transmit corrections to server without relying on the PC internet connection
- by use of IGTS software operating on the PC controlling the permanent reference station connected to the internet.
In some cases owning and maintaining dedicated server connected to internet can create some technical problems and a financial burden; in any case anyone can utilize a dedicated server maintained by INS. Thanks to that, all we need to operate GPS technology in RTK mode of operation is IGTS hardware.
The IGTS module is compatible with the NTRIP protocol; as a result, the system can be used with any caster without the use of a server.
