Skyfield
Skyfield computes positions for the stars, planets, and satellites in orbit around the Earth. Its results should agree with the positions generated by the United States Naval Observatory and their Astronomical Almanac to within 0.0005 arcseconds (which equals half a “mas” or milliarcsecond).Wed Feb 27 11:48:23 2019 - permalink -
Written in pure Python and installs without any compilation.
Supports Python 2.6–2.7 and Python 3.3–3.5.
Has NumPy as its only binary dependency, the fundamental package for scientific computing with Python, whose vector operations make Skyfield efficient.- https://rhodesmill.org/skyfield/

Gpredict: Free, Real-Time Satellite Tracking and Orbit Prediction Software
Gpredict is a real-time satellite tracking and orbit prediction application. It can track an unlimited number of satellites and display their position and other data in lists, tables, maps, and polar plots (radar view). Gpredict can also predict the time of future passes for a satellite, and provide you with detailed information about each pass.Mon Nov 17 00:55:08 2014 - permalink -- http://gpredict.oz9aec.net/

FUNDAMENTALS OF GPS RECEIVERS, A hardware approach. By Dan Doberstein.
This is an all new two volume text, completely revised Jan 2011,Wed Dec 18 22:08:40 2013 - permalink -
text covers how the GPS works from basics all the way through the
operation and implementation of the GPS100SC receiver, a custom
single channel receiver. The text is unique in that not only is
theory covered but the complete details of a functional design
are presented. Detailed schematics (down to part level) and all
design CAD files are included. In addition a chapter is devoted
to the Zarlink chip set, an open software source receiver and all
new material on the Turbo Rogue receiver designed by JPL. There
is no other text like this text. If you want to know how gps
works and how a receiver can be implemented this book is for you.- http://www.dkdinst.com/gpstxt.html

Homemade GPS Receiver
Fairly detailed description of a GPS receiver using 1-bit quantisation, down-conversion, despreading and tracking in an FPGA. The tracking loops are implemented in firmware on a custom Forth-based processor (in the same FPGA), the navigation solution is computed in a Raspberry π (http://www.raspberrypi.org/archives/3916).Wed Jun 26 09:51:23 2013 - permalink -- http://www.holmea.demon.co.uk/GPS/Main.htm

Stanford GPS/GNSS Matlab Platform
Stanford GPS/GNSS Matlab Platform is an integrated research platform for utilizing numerous positioning databases. It is intended to function as a platform providing an universal access to various formats of GPS/GNSS data such as NSTB, NMEA, and RINEX. Example databases include the NSTB stations that collect GPS information continuously in tens of sites and web-available and open to public. According to the presentation (February 2009), RINEX was (is?) not implemented yet.Tue Apr 28 17:30:53 2009 - permalink -
