2020-12-12 Raspberry Pi version
The latest version of the hardware is based on the RPi and is in a bigger box so
it's a bit easier to work with. The FPGA carrier board (upper right) has convenient
test points for measuring delays.
2020-02-09 User manual updated
The rainy weather inspired me to fill in some of the blanks in the documentation.
2020-02-08 Miscellaneous update
Development work of late has focused on improving support for the
ublox ZED-F9 receivers. In particular, there is a new Python logging
script and mktimetx can now decode the GPS ephemeris for
completely self-contained operation. Dual frequency output is now
supported, but still being tested. There will be a poster at EFTF 2020.
Update: EFTF 2020 was cancelled so no poster.
