SENER Aeroespacial, a company of the SENER engineering and technology group, has signed a contract with AVIO for the C/D phases of the navigation unit for the VEGA-C launcher, VNE (VEGA-C Navigation Equipment), after successfully completing phases A (feasibility study) and B (preliminary design).
Phase C involves the development of the detailed design, and phase D is the qualification and delivery phase of the first flight model. This contract paves the way for the mass production of navigation units for subsequent launches of VEGA-C and other space missions.
The navigation unit uses a six-axis compass (position and attitude of the launcher) to provide the rocket's position to the Guidance, Navigation and Control (CNG) system, developed by AVIO, which is necessary to steer the rocket. NAVIGA is thus a critical component for the success of the mission. NAVIGA combines an Inertial Measurement Unit (IMU) and a Global Navigation Satellite System (GNSS) receiver, and hybridizes the two readings to achieve a high-performance product – its software is Class A, the most critical in the space industry – but also low-cost compared to the inertial navigation units available on the market.
