Two range records (L1 & L2) are produced for each SV which exceeds buffer allocated for 12 SV >How-To-Repeat: Turn on debug in NovatelData.cpp, recompile and read appropriate data file with novaRINEX. >Fix: Increased size of buffer in NovatelData.hpp Used sizeof and corrected determining if a buffer overrun will occur for OEM2 and OEM4 receivers in NovatelData.cpp. Patch files attached.
