PELORUS/HONEYWELL SYSTEM UPDATE.CALGARY, ALBERTA--(BUSINESS WIRE)--MARCH 27, 1995--PELORUS NAVIGATION(Alberta Stock Exchange Alberta Stock Exchange See Canadian Venture Exchange (CDNX). : PN) The Pelorus/Honeywell Satellite Landing System, SLS-1000, operates with three DGPS (Differential GPS) See GPS augmentation system. receivers installed at precisely surveyed locations and referenced to and dispersed around a precisely surveyed point on a runway. The receivers each determine the differential corrections necessary to remove the errors in the satellite signals received due to the effects of the ionosphere ionosphere (īŏn`əsfēr), series of concentric ionized layers forming part of the upper atmosphere of the earth from around 30 to 50 mi (50 to 80 km) to 250 to 370 mi (400 to 600 km) where it merges with the magnetosphere, the region , troposphere troposphere: see atmosphere. troposphere Lowest region of the atmosphere, bounded by the Earth below and the stratosphere above, with the upper boundary being about 6–8 mi (10–13 km) above the Earth's surface. and selective availability (SA). The ground station processes the data from each DGPS receiver and after ensuring the integrity, transmits the correction message once per second up to the airborne DGPS receiver. The airborne receiver is equipped to apply the corrections and produce navigation data that is accurate to within 1.5 meters horizontally and 2 meters vertically. In addition to the minimum requirements for compliance, the Pelorus/Honeywell system also transmits the precision approach Path Points for all approaches in the local area. Work on the project already has started. Pelorus pe·lo·rus n. pl. pe·lo·rus·es A fixed compass card on which bearings relative to a ship's heading are taken. [Origin unknown.] has awarded a contract to SED Systems of Saskatoon to assist with the product development. Pelorus will scale up its production facility in Saskatoon in early 1996 to coincide with global marketing activity and certification of the Saskatchewan installations by Transport Canada. Pelorus expects to create six high tech jobs initially with expansion planned as the global market increases. The estimated requirement for LDGPS LDGPS Local Area Differential Global Positioning System could run into the $8 billion range over the next 50 to 10 years.
