This page contains all the information about the project: theoretical algorithms, implementations and all the results obtained so far.

The base paper is available here for free. We detail all the information in the following sections.

NOTE: All files are stored in our public FTP. You can enter the FTP ftp.sgpsproject.org with username anonymous@sgpsproject.org and leave the password blank. Other easier option is to use the following link directly: ftp://anonymous@sgpsproject.org@sgpsproject.org This FTP is not working/necessary anymore.

Theoretical

Base System Description: Definition of the basic system, what are its objectives.

Celestial Model: Formulae to find out the earth coordinates using sunlight.

Simulations: Testing the algorithm supposing a perfect sunrise and sunset detection.

Equation of Time: What it is and how to use it.

Fractional days: Why are a problem and how to manage them.

Limitations: Known limitations so far.

Equinoxes: Why they are a problem.

NOTE: We think that it is better to go to the MAIN SGPS PAPER for the basic theoretical information (the information previously displayed here was pretty much the same).

  • Angle-based SGPS: (Under development) Current research on how to compute the localization from the incidence angles of the sun on the earth.
  • SGPSNet: SGPS Network, first steps towards a self-locating Wireless Sensor Network with SGPS.

Implementations and Software

  • Basic C/C++: Base program written in C/C++ to analyze sunlight data.
  • Iterative SGPS: Matlab/Octave algorithm to find out the coordinates by Iterative ICM (Inverse Celestial Model).
  • Android SGPS: An implementation for testing the SGPS in Android devices.
  • SGPSNet: The source code is included the explanatory page.


Data

  • SGPS Results: Files containing the results of the application of the basic SGPS algorithm to the NOAA FTP dataset.
  • SGPS Network results: Given together with the source code. The results are in data/results.mat. More info in the README file included and in SGPSNet.

Results

The main experiment we carried out is detailed in the MAIN SGPS PAPER using NOAA FTP dataset and the Basic C/C++ program.

  • AA+ Library: It is a C++ implementation for the algorithms as presented in the book "Astronomical Algorithms" by Jean Meeus.
  • LDR GPS: The same idea as SPGS but a little bit simpler. Based on the AVR Butterfly module.
