  The Cape, Chapter 3, Section 4, NAVSTAR II Global Positioning System Missions
The NAVSTAR II-3's first launch attempt on August 12th was scrubbed due to a weather constraint violation at launch time, and a second countdown was required before the vehicle lifted off Pad 17A at 0557:59Z on 18 August 1989.
The NAVSTAR II-4 mission was launched from Pad 17A on its first launch attempt at 0931:01Z on 21 October 1989, but the NAVSTAR II-5 mission was scrubbed on 10 December 1989 due to a helium problem in the vehicle's second stage.
The NAVSTAR II-16 countdown on November 7th was scrubbed at 0105Z due to a vehicle misfire, and the mission's next countdown on November 20th was scrubbed at 0005Z due to weather constraints.

 Space Today Online - Satellites - NAVSTAR global positioning system GPS satellites
The NAVSTAR system consists of a constellation of orbiting satellites, a ground control system, and thousands of GPS receivers in use on the ground and in the air.
NAVSTAR Control Center at Colorado Springs, Colorado, checks the satellite clocks regularly to make sure they are beeping in sync.
Despite the military heritage of the NAVSTAR system, handheld and mobile GPS receivers giving locations in latitude and longitude are sold to civilians by stores and catalog merchants around the world.

 The Cape, Chapter 3, Section 2, Evolution of the NAVSTAR Global Positioning
By the end of 1980, the NAVSTAR GPS constellation was arranged in two orbital planes of three satellites each, orbiting Earth at an altitude of approximately 10,900 nautical miles.
NAVSTAR Support facilities were the next order of business: as Block II satellites and PAM-DII modules arrived at the Cape, they were to be mated to each other in a NAVSTAR Processing Facility (NPF) modified expressly for that purpose.
Only two NAVSTAR II satellites remained on the Shuttle's manifest by the end of FY 1988, and those last two spacecraft were reassigned to the DELTA II in the spring of 1989.

NAVSTAR SV orbits are arranged such that they pass within communications of one of the NAVSTAR Control Segment monitor and/or ground stations (discussed below) every 24 hours.
The NAVSTAR Monitor Stations are used to accurately measure signals received from NAVSTAR SVs, preprocess these signals, and send the resulting data to the NAVSTAR Master Control Station.
Data from Monitor Stations is used by the NAVSTAR Master Control Station to calculate required corrections to current SV ephemeris and clock data; the Master Control Station also maintains status on all SVs and performs mission planning functions.

 Global Positioning System - Wikipedia, the free encyclopedia
United States Department of Defense developed the system, officially named NAVSTAR GPS (Navigation Signal Timing and Ranging GPS), and the satellite constellation is managed by the 50th Space Wing at Schriever Air Force Base.
Although the cost of maintaining the system is approximately US$400 million per year, including the replacement of aging satellites, GPS is available for free use in civilian applications as a public good.
GPS allows accurate targeting of various military weapons including cruise missiles and precision-guided munitions, as well as improved command and control of forces through improved locational awareness.

This screen also has the settings that allow Navstar to be coupled with FS98's autopilot, and define holding patterns (more on that later).
The Navstar computer will automatically calculate an altitude based on the distance and begin a descent so your aircraft will arrive at the altitude calculated.
You can decide whether the holding pattern should be inbound or outbound, direction, which is usually the current heading, which way the aircraft should turn and how long in either time or distance the aircraft should stay in the pattern.

 NAVSTAR Redesign -- Executive Summary   (Site not responding. Last check: 2007-10-23)
The NAVSTAR Global Positioning System (GPS) is a US Department of Defense system that allows users to determine their precise location (within 10-100 meters) at any point on the surface of the earth.
It was designed in the late 1970s/early 1980s; after a prolonged period of deployment and testing, NAVSTAR achieved full operational capability in 1995.
Processing power available is literally orders of magnitude greater now than in the early 1980s; telecommunications speed and reliability has improved dramatically; and object-oriented approaches dominate the software development process rather than the procedural orientation of the early 1980s.
