DESCRIPTION AND OPERATION

1. 

General

A. Presentation

The Receiver Processor Unit (RPU) is built into the GPS (Global Positioning 

System) navigation system NSS100S-1 (Navstar Sensor System type 100-1 SPS).

It can operate with an active or passive antenna (ACU), and with a preampli-

fier (PAU); these three units make up the user segment.

The antenna (ACU) picks up signals transmitted by various visible satellites 

(as many as 8).  These signals are amplified by the preamplifier (PAU) and 

sent to the Receiver Processor Unit (RPU).

This RPU simultaneously analyzes and processes the signals transmitted by 

the satellites (maximum of 8), in order to calculate a position-fixing so-

lution expressed in time and in three dimensions; after processing the data 

contained in the satellite signals, the RPU calculates and transmits the air-

craft position, speed and time parameters.

B. Main Functions

- Acquisition in C/A code (Coarse Acquisition code) and tracking of signals 

transmitted by satellites in the parallel mode over 8 channels (using 

L1/L2 receive frequencies).

- Measurement of pseudo-distances and pseudo-speeds that correspond to the 

satellites used.

- Fixing and maintenance of aircraft position and geographic speed based on 

GPS measurements; position determination is based on the SPS system (Stan-

dard Positioning Service).

- Determination of GPS and UTC (Universal Time Coordinated).

- Taking into account parameters available on the input/output interfaces 

and use of these parameters to improve performance (jamming resistance, 

aircraft dynamic resistance, acquisition time...), depending on the 

configuration.

- Self-test of GPS equipment functions and characterization of the quality 

of information provided concerning position, speed and time.

This characterization includes detection of operational anomalies in the 

space segment, whenever possible (particularly when 5 or more satellites can 

be used).

- Demodulation of navigation messages transmitted by all satellites tracked, 

management and permanent memory storage of the GPS constellation almanac.

- Maintenance of GPS time, equipment switched off for easier initialization.
