三星GPS模块资料,13MMX16MMX2.5MM,

这个程序能很智能地计算贴片天线的各个参数，只要给出其中的任意参数就能计算出其他-This process can be very smart to calculate the various parameters of patch antenna, as long as give them any other parameters can be calculated

GPS中NEMA协议的校验值的计算，一字节模和计算工具。用于校验和计算。

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.
