Notes

- Three GNSS loggers were installed in June 2023 by Shore Monitoring and Research
to monitor ground motion in the framework of the Nationaal Onderzoeksprogramma Broeikasgassen
Veenweiden (NOBV). Two loggers, called Lidar and Ref, use antennas installed on a grid to
monitor the motion of the top soil, similar to the setup in Weerribben. The third, called
Veenmos, next to Lidar, with the antenna mounted just above the ground on a very light weight
plastic construction, is specifically constructed to monitor the growth of Veenmos.

- On 3 September 2023 cows escaped and entered the measurement plot. It is not known if the
the antenna setups were disturbed.
- 2023-09-12T23:59 2279/2 255 - 2024-10-26T12:00 2337/6 300
- No data was logged during this period. Since early September both Raspberry Pi loggers were
experiencing problems and after 12 September 2023 no data was logged at all. On 19 January
2024 both raspberry pi loggers were removed from the site for inspection and not reinstalled.
They raspberry pi's were found to be disfunctional, but data
for up to 12 September was retrieved from the SD cards using another raspberry pi.
- 2024-01-19T10:00 2297/5 019 -
- The voltage on the cables providing power to the gnss logger installations was changed
from 230 V AC to 12.V DC. The adapters inside the gnss logger installations were disconnected,
a new adapter was installed in the cabinet which provides power the other sensors on the plot.
- 2024-10-25T11:00Z 2337/5 299 -
- In October 2024 TU Delft took over responsability for the GNSS loggers and processing
from Shore Monitoring and Research.
On October 25 and 26 2024 new data loggers were installed, but the receiver and antenna
hardware remained the same (execpt for a firmware upgrade of the receivers).
On the plot with two receivers (VEENMOS and LIDAR)
a GL-iNet X750 4G OpenWrt router with UbxLogger software was installed, on the plot with a
single receiver (REF) a Rapberry Pi 4 with UbxLogger software, connected to the GL-iNet by WiFi.
The firmware of the receivers was updated to 1.32. The antenna's were not changed (except for
clearing some grass around VEENMOS). Logging was resumed on Oct 26, 2024, around 12:00 UTC.

- The nearest base station for the processing is a GNSS station in Amsterdam, operated by 06-GPS, at a
distance of 6.2km.

- The receiver did not output UBX-RAWX messages until 2023-07-31T14:41Z, only NMEA data was recorded.
- 2023-09-03T12:00Z 2278/0 246 - 2024-01-19T12:00Z 2297/5 019
- On 2023-09-03T12:00Z the logger started to having problems logging data, resulting in serious gaps, until
logging was stopped on 2023-09-08T07:46Z. One more hour of data was recorded on September 12, but nothing
after that.
On 2024-01-19 the raspberry pi logger was returned to the office for inspection.

- On 2023-08-31T06:24 the logger stopped logging data. Logging was resumed intermittendly on 2023-09-01T05:49,
but many days without any data, other days with only about one hour (around 6 AM). After 2023-09-11T14:00 no
data was logged at all. On 2024-01-19 the raspberry pi logger was returned to the office for inspection.
