    Abstract
    In June, 2005 the flight of a microgravitational space platform (MSP) “Foton-M2” was realized. On board “Foton-M2” the apparatus developed at the Samara State Aerospace University has been located. Its assignment was definition of environment parameters in which research experiments as inside as outside of a platform were conducted. The first time on MSP the experimental 16-channel GPS/GLONASS receiver which worked together with the magnetometer has been established.
The purposes of navigational experiment were:
- Improvement of principles of construction of the auxiliary navigational system intended for tracking of research experiments in orbit, and also navigational technology which further can be used at creation of small satellites;
- Maintenance of high-precision time-position registration of all experiments conductive on MSP;
- Improvement of algorithms of MSP motion recovery (as center of mass, and concerning center of mass) in conditions of breaks of the information receipt, caused by its non-oriented flight;
- Improvement of algorithms on construction of “true orbit of motion” as a result of post-flight processing measurements;
- Research of a capability of increase of accuracy of satellite radio navigation due to engaging the additional measurements conductive synchronously on ground center with use of the analogous receiver when MSP flew in a visibility zone of ground center;
- Research of a capability of an integration of data from the navigational receiver and the magnetometer at definition of orientation and angular rate of MSP motion concerning center of mass;
- Functional check and an estimation of real characteristics of the experimental navigational receiver;
- Research of influence  MSP telemetering system and the ground centers executing transfer control commands to MSP on signal detection from navigational satellites;
- Improvement of MSP flight information support technology in a mode of a near-real time, due to creation of 'virtual MSP' in the INTERNET with use of data from the navigational receiver and the magnetometer acting together with telemetry.
The magnetometer and the navigational receiver have worked within 220 hours (about 10 days) pursuant to the allocated resources on MSP. Data of measurements were saved in flash memory which has been returned to the Earth inside recoverable capsule. As a whole experiments were carried out successful. Results of experiments are demonstrated, the characteristics to the used algorithms and the specialized software are given.
