Many GPS receivers can relay position data to a PC or other device using the NMEA 0183 protocol. Although this protocol is officially defined by the National Marine Electronics Association (NMEA), [ 110 ] references to this protocol have been compiled from public records, allowing open source tools like gpsd to read the protocol without ...
A-GPS protocols are part of Positioning Protocol defined by two different standardization bodies, 3GPP and Open Mobile Alliance (OMA). Control Plane Protocol Defined by the 3GPP for various generations of mobile phone systems. These protocols are defined for circuit switched networks. The following positioning protocols have been defined.
A surveyor uses a GNSS receiver with an RTK solution to accurately locate a parking stripe for a topographic survey. Real-time kinematic positioning (RTK) is the application of surveying to correct for common errors in current satellite navigation (GNSS) systems. [1]
GNSS systems that provide enhanced accuracy and integrity monitoring usable for civil navigation are classified as follows: [5] GNSS-1 is the first generation system and is the combination of existing satellite navigation systems (GPS and GLONASS), with Satellite Based Augmentation Systems (SBAS) or Ground Based Augmentation Systems (GBAS).

Galileo Control Centre at the DLR Oberpfaffenhofen site Galileo In-Orbit Test (IOT) L-band (1,000 – 2,000 MHz) antenna at ESTRACK Redu Station. The system's orbit and signal accuracy is controlled by a ground segment consisting of: Two ground control centres, located in Oberpfaffenhofen and Fucino for Satellite and Mission Control
The "mystery drones" over the East Coast have sparked concern from local residents, some of whom are flocking to neighborhood surveillance apps to post about the topic.

A software GNSS receiver is a Global Navigation Satellite System (GNSS) receiver that has been designed and implemented using software-defined radio.. A GNSS receiver, in general, is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position, velocity and time (of the receiver).
