Abstract The article is devoted to navigation complex based on autonomous short-range radio navigation system. The complex provides precise definition of object location without satellite radio navigation system signals. Operation principle of short-range radio navigation system lies in simultaneous measurement of ranges between the object and several reference navigation devices with known coordinates. Range-finding equipment includes on-board radio electronic module and set of fixed modules (beacons). The processing of the measured ranges in the navigation complex computer allows for the moving vehicle coordinates. Depends on moving vehicle type configuration of the navigation complex involves additionally MEMS-based strapdown inertial navigation system, barometric and laser (for aerial vehicles) altimeters. Autonomy, noise immunity and high rate of measurements are among the main advantages of suggested complex. Preliminary procedures of terrain reconnaissance for rational beacons installation, range-finding equipment calibration and also schemes and algorithms of integrated processing of different systems navigational data are observed in the paper. The results of field test with model pattern provided conclusion about satisfactory precision of the navigation complex without the use of satellite radio navigation systems are given.
