WIMR – Where Is My Rover
Global and local positioning of a Mars exploration robot
Funded by ESA under 2nd Polish Industry Incentive Scheme
Project value 200 000 EUR
Completed: September 2016
Rover path calculation (WIMR 1A)
Additional tasks: stereo imagery processing (WIMR 1B)
Lander descent trajectory (WIMR 2A)
Landing position recognition (WIMR 2B)
Horizon recognition (WIMR 3)
2 software applications
Specifications of data sources and hardware configurations have been defined as closely complying to the accepted Mars mission development plans.
The most important ones were:
10% relative localization accuracy in total traverse No artificial landmarks MRO HiRise imagery resolution as reference Strict data budget and Ground-based processing Defined camera and sensor specifications
Compilation and systematization of positioning processat different stages.
Exploring of positioning problems.
Compilation of affine transformations for path calculation.
Compilation of projective transformations for descent trajectory calculation.
DEM sectioning for horizon calculation.
Unified parameter set format for seamless adding of new data sources.
Data budgets were analyzed and defined.
Operator’s roles were defined.
TRL 4 was achieved (from initial TRL3)
