GPS (global positioning system)

Geoid

Telecommunications; GPS (global positioning system)

The fundamental surface in Geodesy. It is defined as the equipotential surface of the gravity field that most closely approximates the Mean Sea Level. (The MSL deviates from the Geoid surface by 1-2 ...

Geosynchronous orbit

Telecommunications; GPS (global positioning system)

A specific orbit around where a satellite rotates around the earth at the same rotational speed as the earth. A satellite rotating in geosynchronous orbit appears to remain stationary when viewed ...

Multi-channel receiver

Telecommunications; GPS (global positioning system)

A GPS receiver that can simultaneously track more than one satellite signal using a dedicated signal electronics channel for each satellite. High quality receivers may have 12 channels for L1, and ...

Multipath

Telecommunications; GPS (global positioning system)

Interference caused by reflected GPS signals arriving at the receiver, typically as a result of nearby structures or other reflective surfaces. May be mitigated to some extent through appropriate ...

Multipath error

Telecommunications; GPS (global positioning system)

Errors caused by the interference of a signal that has reached the receiver antenna by two or more different paths. This is usually caused by one path being bounced or reflected. The impact on a ...

Multiplexing channel

Telecommunications; GPS (global positioning system)

A channel of a GPS receiver that can be sequenced through a number of satellite signals. In contrast to a Multi-Channel Receiver in which one channel is dedicated to each satellite signal.

Multiplexing receiver

Telecommunications; GPS (global positioning system)

A GPS receiver that switches at a very rapid rate between satellites being tracked. Typically, multiplexing receivers require more time for satellite acquisition and are not as accurate as parallel ...
