GPS Monitoring System

DWI has developed the GPS Monitoring System (GPMS) offering performance prediction analysis and real-time fault monitoring so airport operators can comply with ICAO guidance concerning the recording of GNSS availability data and GNSS operational status.

The GPS Monitoring System (GPMS) allows users to comply with ICAO guidance, Annex 10 (Chapter 2 of Volume I, in paragraphs 2.4.3.1 and 2.8.1 respectively):

  1. A State that approves GNSS-based operations should ensure that GNSS data relevant to those operations are recorded. These recorded data are primarily intended for use in accident and incident investigations.
  2. Aerodrome control towers and units providing approach control service shall be provided without delay with information on the operational status of radio navigation aids essential for approach, landing and take-off at the aerodrome(s) with which they are concerned.

GPMS consists of 2 modules: Local Area Monitoring and Receiver Monitoring.

Local Area Monitoring

Local Area Monitoring (LAM) continuously monitors actual GNSS accuracy and integrity, and determines the current availability of GNSS navigation services at the location of a GNSS monitoring receiver antenna. LAM generates and reports current results in realtime and displays the following metrics:

Receiver Monitoring

The Receiver Monitoring tool continuously monitors the operating status of one or more GNSS receivers simultaneously. The GPMS Receiver Monitoring Tool is configured to monitor the integral GNSS receiver(s) that is used to obtain input data from GNSS satellites. It offers the following data:

Implementation

DWI oversees all aspects of the tailored design of the GPMS, selection of equipment appropriate to local conditions, installation and training of usage.

GPMS can be combined with DWI's GPS Raim Prediction Service service to give a local and Wide-area RAIM monitoring and prediction service.
