Open Source GPS Software

The Orbit Determination Toolbox (ODTBX) is developed by the Navigation & Mission Design branch at NASA Goddard Space Flight Center as an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, and/or rapid design center environments. ODTBX functions and utilities are combined in a flexible architecture that allows for modular development of navigation algorithms and simulations. The core ODTBX functionality is realized through a set of estimation commands that incorporate Monte Carlo data simulation, linear covariance analysis, and measurement processing at a generic level.

This is an Android App for 2.3.3 Android OS and above. It deals with Hard- and Software Sensors which are integrated in Nowadays Smartphones. The User can select the Sensors and observe the current values of - Accelerometer - Gyroscope - Magnetometer - GPS Position - .... and other Sensors A Stream containing the Sensor-Values in CSV- Format by WLAN To a Client and/or a Stream To a SD-Card can be started and stopped. The Sensor-Update frequency can be adjusted. There are some GPS-Algorithms running in the Background which transform the GPS data in different coordinate frames. The Stream via WLAN uses the User Datagram Protocol (UDP) Interface. In order to receive the data you can use something like the Java File "QuoteClient"in the Files-Section.

With this Android Gps Pro application, you can get raw GPS data and take screenshots in order to remember the actual GPS coordinates of your Android device.

This project is designed to be able to take standard NMEA data available from most boats and broadcast APRS WX reports. Other telemetry like battery voltage, tank levels, etc, as well as data logging will be supported.

OpenPMU is a collaborative project developing a software defined Phasor Measurement Unit for Smart Grids and electrical utilities. This project is currently hosted by Queen’s University Belfast.
