Currently, Supergeo's product team is developing the support for
RTCM 3.1, including Type 1021 and 1023, two kinds of messages.
All experiments used the
RTCM message as a principal data format, and CMR/CMR+ was also used for some VRS operations.
ERGNSS provides positioning services for high accuracy applications, including downloading of GNSS data (GPS+GLONASS) in compressed format and also provides RTK services, transmitting single-based reference station corrections in
RTCM format using the NTRIP protocol (Network Transport of
RTCM via Internet Protocol) (Weber et al., 2005).
The United States, Federal Communications Commission (FCC) has now mandated that in future, any new products in the related categories must be tested using a GNSS simulator and the scenarios in the
RTCM standards, which were developed by Spirent.

Aunque las mediciones en tiempo real existen desde hace varios anos y en distintas modalidades, son aquellas basadas en las correcciones NTRIP (Network Transportation of
RTCM via Internet Protocol), las que estan a la vanguardia y apuntan a consolidarse como una de las mejores opciones cuando se trata de obtener coordenadas confiables en el mismo instante de la observacion, esto debido principalmente a la simplicidad y flexibilidad del metodo.
They are compatible with CORS and other RTK reference networks where open architecture formats such as
RTCM v3 and CMR/CMR+ messages are provided.
It showed that the Internet-based NTRIP (Networked Transport of
RTCM via Internet Protocol) standard can also be used to safely transmit huge data volumes and different data formats to a large number of users.
