Tips and questions relating to the GPS modules from SFE
By davidj6
I am investigating a high-altitude project and would like to use GPS for data logging. Most products have an altitude max listed of 60k ft. Does anyone know if this altitude can be exceeded reliably or is there an embedded GPS product that will work up to 100km?
