Kodiak: A versatile special purpose multi-GNSS receiver for highly dynamic sounding rocket applications

Abstract

The Kodiak GNSS receiver is a modular and versatile GNSS receiver platform that has been developed by DLR specifically for high dynamic space applications such as sounding rockets, launch vehicles or re-entry vehicles. It is a successor to the widely used Phoenix GPS receiver. Its flexible design allows various use cases like rocket- or other high dynamic applications. Features are: estiamation of the 6DoF state of vehicles by fusing the receivers position and velocity with the inertial navigation solution, orientation estimation from relative carrier phase measurements of signals of two or more antennas, adaption of tracking depending on the flight phase forecasting of Doppler frequencies based on current velocity estimations of the IMU solution. This paper presents first flight results of the Kodiak receiver.
