Problem

The satellite subpoint coordinates and pseudo-ranges for the four GPS satellites whose signals are received by a positioning radio are shown in Table 1. All pseudo-ranges are given relative to the first satellite position.

	Sat 1	Sat 2	Sat 3	Sat 4
Longitude	-62.3256	-85.2234	-90.9760	-95.0234
Latitude	43.2345	35.5521	29.0510	40.7777
PR/c (s)	0.000000000	-0.00158701	-0.00137326	-0.001090228

Table 1: Satellite Coordinates and Time

Other parameters given are:
-Mean earth radius: 6,380.00 Km
-GPS satellite altitude: 20,200.00 Km
-Speed of light (c ): 299,860.00 Km/s

Based on this data, the problem is to calculate the longitude, latitude, and altitude for the GPS receiver.
