Subject: New ESA GPS receiver at Malindi (MALI)
A GPS receiver has been installed at Malindi, Kenya, in
the ESA San Marco Telemetry station. The receiver is a
MiniRogue SNR-8C with the antenna DORNE MARGOLIN B
mounted on a new geodetic monument.
We are currently retrieving the data to ESOC daily using
the communication links that have been set up for other
ESA projects and that could be discontinued, but a
dedicated solution for the receiver seems to be feasible.
We are experiencing problems with the high drift of
the internal frequency reference of the receiver,
around 300 ns/s. We are planning a test this week
using an external (also quartz) reference available
on the station.
Data are available from DOY 316/95 on. They will be
distributed to the data centres.
An approximate set of marker coordinates is the following:
X: 4865.366 Km
Y: 4110.740 Km
Z: -331.122 Km
A copy of the station information form is included below.
Best regards.
