Abstract :
The paper starts with a brief consideration of a novel bistatic SAR experiment and the requirements on attitude and position determination in SAR. GPS/INS integration strategies are summarized. To obtain an affordable system for the antenna pointing for footprint chasing, low-cost inertial measurement units are in the focus. By an observability analysis it is proven that additional redundant attitude information as it can be derived from a multi-antenna GPS receiver can remarkably aid the integration.
