Review on Black GlobalSat BU-353-S4 USB GPS Receiver by Joseph Flamm

This is my third. I use them on Windows 10 64-bit machines to optimize the time taken by some applications I run (Meteor Scatter communication in DATA MSK144 mode). The puck comes with a minidisk that contains a utility called GPSinfo. While this utility is running, your windows time will not be running. (Make sure you turn off Windows' internal time setting so they don't compete). It is highly recommended to use the NMEATime2 software as an optional extra. Here is the result of using this GPS as a time reference: seconds) I ran the program and GPS 24/7. I can see 7 satellites from my basement using a GPS repeater purchased from Revain with the antenna attached to a broomstick opposite the SE window just above the ground. The sensitivity is great! For those interested in technology, the HDOP is currently 1.9 and the PDOP is 2.5. For reference, anything under 4 is considered GREAT.
