We are replacing the antenna and the receiver of the CASC00PRT station.
We will disconnect data from day 261 at 10h UT.

The new equipment will receive the Galileo signals.

As soon as possible we will connect the station again.

[EUREFmail-09985] - 2019-09-24 (26/09/2019)

The CASC receiver and antenna have been replaced.
The receiver is Trimble Alloy with 5.37 firmware version.
The antenna is a choke ring: TRM159900.00.

This upgrade allows CASC station to receive Galileo signals.

An updated sitelog has been resubmitted to M3G.

[EUREFmail-9285] - 2018-02-05 (16/02/2018)

Due to the need of maintenance services in the Portuguese CORS GNSS network, all
services for the stations CASC, FLRS, FUNC, GAIA, LAGO and PDEL will be
inoperative between 2018-02-14 (DOY 45) 12:00 UT and 2018-02-23 (DOY 54) 20:00 UT.

There will be no hourly files for this period.

The dayly files will be uploaded as soon as possible.

[EUREFmail-9095] - 2017-07-21 (21/07/2017)

Due to a power failure at the fortress where the CASC station is located, data
from CASC were missed between DOY 201l and DOY 202j.
