Abstract

The paper studies the possibility to use MEMS-based integrated INS/GNSS systems in the automatic control systems of precision airdrop systems (PAS ACS). Experiments have been conducted to find a navigation solution during the parachute descent. The PAS ACS prototype with remote control and guidance based on the data of a MEMS-based integrated INS/GNSS system has been developed. Flight tests of the designed prototype have been carried out.

Abstract

The Nimbus Project team, made of young engineers and university students, is developing an Autonomous Re-Entry System (ARES) based on a controlled paraglider. The target is to use the ARES to autonomously recover a reusable sounding rocket in a specific area dedicated for landing. The system is mainly divided in two parts: the paraglider wing with a traditional configuration of a ram-air parachute and the control box which houses the main control electronics. Furthermore, the sounding rocket is attached to the control box and a ground station receives telemetry or sends telecommands for both the rocket and the control box. In order to test the system in-flight independently from the launch of a rocket, a fully functional Technology Demonstrator has been developed. It is built from Commercial-Off-The-Shelf items and components and from custom composite parts. The mass of the wing is about 200g for a surface of 1.1m2 and the control box mass is 550g. The electronics communicates through telemetry and telecommands with a ground PC. Attitude and position sensors are used in the control loop and three modes of operation can be selected. The ARES has been already flight tested in direct control mode.
