Origin: Formed within English, by compounding. Etymons: minimum adj., tracking n.¹

Etymology: < mini- (in minimum adj.) + track- (in tracking n.¹), after the fuller name minimum-weight tracking.

A system for tracking satellites by means of a lightweight oscillator placed in the satellite, whose position is calculated from the phase difference between radio signals received by each of a spaced pair of aerials on the ground. Usually attributive.

1956 Spaceflight 1 27/2 A system of radio triangulation, called Minitrack, using phase comparison techniques, will establish the satellite's position and orbital path.

1961 Daily Tel. 18 Jan. 20/4 One of two remote-controlled rotating aerials at the minitrack radio tracking station at Winkfield, Berks, which is now nearly ready to go into operation.

1974 G. Perry in H. Miles Artificial Satellite Observing vii. 145 The NASA Minitrack system provides directional observations with an accuracy of about 100 seconds of arc.

1991 R. Wohlleben et al. Interferometry in Radioastron. & Radar Techniques viii. 131 At the time the US Minitrack interferometric network was developed, the orbits of satellites were planned as circles.
