Objective: to develop and experimentally test hardware and software based on a GPS receiver that will ensure the accumulation of single-frequency GPS/GNSS data and their transmission from the consumer to the observation processing centre.
Main results of the work.
Hardware and software based on a GPS receiver have been developed that provide the accumulation of GPS data and their exchange between the consumer and the observation processing centre:
- data transmission (GPS/GNSS observations) from the consumer to the automated processing centre of the GNSS information and measurement system using GSM/GPRS mobile communications;
- reception and decoding of messages in NTRIP format, allocation of appropriate DGPS/RTK corrections in RTCM 2.3 format and implementation of differential determination mode in the consumer’s equipment.
