RVSA/B Receiver Status
This log conveys various status parameters of the receiver system. If the system is a multiple-GPSCard unit with
a master card, certain parameters are repeated for each individual GPSCard. If the system is composed of only one
GPSCard, then only the parameters for that unit are listed. Together, the RVSA/B and VERA/B logs supersede
the RCSA/B logs.
Note that the number of satellite channels (the number of satellites the receiver is capable of tracking) is not
necessarily the same as the number of signal channels. This is because one L1/L2 satellite channel requires two
signal channels. Therefore the 12-channel MiLLennium GPSCard will report 24 signal channels in this field. This
number represents the maximum number of channels reporting information in logs such as ETSA/B and RGEA/
B/D.
