  3. Python-based program which performs RSS-based fingerprinting and clustering-based indoor position estimation with WLAN signals. Created by Andrei Cramariuc, @TUT. The link includes also training and estimation WLAN measurement data. The Python-based program has been tested only in Linux; for other operating systems, modifications may be needed. Research papers to use this data could cite the following paper:

Measurement data for wireless positioning
  1. Indoor WLAN measurement data in two four-floor buildings for indoor positioning studies. The data contains the collected RSS values, the Access Points ID (mapped to integer indices) and the coordinates; both the training data and several tracks for the estimation part are provided. The data can be used with any indoor localization algorithms, such as fingerprinting, path loss probabilistic approaches, Dempster Shaffer decision theory, etc. A Readme file is included. Research papers to use our measurements data could cite the following two papers, where also benchmark results based on this data are provided:

  2. GSM and UMTS urban measurement data for cellular-based positioning. The data has been collected in Tampere with a Nokia phone. The data is given in Matlab *mat format and it contains a cell variable called BS_grid* which shows the GPS coordinates (converted in local coordinates, in meter values) and the collected RSS value per transmitter (i.e., BS or Node B). Example of research results based on these measurements can be found for example in:

  3. 50000 multi-GNSS constellation points covering the full constellations of GPS, Galileo, Beidou-2/Compass and Glonass. Generated based on a Spectracom GSC-64 simulator. Research papers this data could cite the following paper, where also benchmark results based on this data are provided:
