This paper presents a research work to develop a navigation technique for a class of nano-micro space rocket. Onboard MEMS inertial sensors are used in view of post-flight trajectory estimation. Combined with synchronized measurements of the combustion engine which is of hybrid type and uses N2O and PE, we show how the relative redundancy of the data can be used to calibrate a thrust model. Experimental results are presented and stress the numerous difficulties needed to be resolved. Quantitative results are provided along with estimates of the obtained accuracy.
