Telemetry system for very high acceleration

Hybrid radio transmission electronic modules designed for telemetry utilization and inclusion in gun projectiles are described. The dimensions of each module are 10 x 10 x 2 mm and they can be used in projectiles with a minimum of 20 mm diameter. The effective transmission trajectory range varies from 1 km for 30 mm projectiles to 30 km for heavy artillery projectiles. A large variety of measurements are possible including ballistic, aerodynamic, mechanical, and physical parameters. The circuits of several modules are detailed.
