Dundee Satellite Station Ltd
Dundee Satellite Station Ltd
is setting up new premises at Errol and will be offering a range of
services to the UK and International Space sector including
reception and transmitting facilities in VHF, UHF, L-band, S-band,
X-band and Ku-band as well as a range of consultancy services around this
from RF through to data processing software, and integration to
existing systems. We can provide quality support from your initial design
phase looking at comms options and link budgets, through to "premium"
ground station support (e.g. signal analysis and recording, orbit
determination, etc) during critical phases such as
LEOP
or following anomalous behaviour, and on to cost-effective routine
operations for data up and down links.
In addition to these spacecraft-operation support services
we will be receiving Earth Observation data in real-time with a view
to supporting both time-sensitive commercial applications as well as
providing a broad range of archive data access for research and
general public interest purposes.
Further down the line we are already in discussion with other
organisations with a view to providing an integrated service offering
greater geographic coverage over more of Europe and with additional benefit
of multiple-site resilience.

First Overhead Pass of 2021
This infra-red images was taken by NOAA-19 on a south-bound pass, overhead at 07:51 on
Friday 1st Jan 2021, which we re-projected to this 1024 x 1024 sized image (with the
5 degree grid lines and coast automatically overlaid).
You can also get a
4k x 4k version which is 12MB and shows
the resolution limit of the AVHRR scanner. However, it is still impressive for
an instrument that was first flown in 1978 on the TIROS-N satellite!
Terra 21st Birthday Fri 18th Dec 2020
The satellite Terra was launched on the 18th Dec 1999 and today has
its 21st birthday, an unusually long time for any satellite to remain
in operation. While the MODIS sensor is showing some signs of degradation
and it has been largely replaced by the newer NPP and NOAA-20 birds, it
is still worthy of note. This quick look-image was taken around 12:03
today and shows the weather features bearing down on the UK.
Errol Antennas
As well as taking this (and other) passes, we have got to the stage of having
two tracking antennas in routine operation, though sadly not with any web site or
other service to make the received data available to the outside world. That
is something we hope to fix in 2021.
For now we can at least show a picture of those two antennas tracking, along
with those still to be refurbished and put back in to service.
First Pass Tue 15th Sep 2020
We were able to receiver our first images at the new RAF Errol site
using our 3.7m antenna with the X-band feed formally used in Dundee.
While we still have a long way to go to be fully operational, it is
good to finally see something in return for our efforts and all of the
support we have been getting.
The current 3.7m pedestal dates from 1997 (though the reflector is from 1975)
and was constructed to allow DSRS to take data from the NASA EOS satellites
Terra and Aqua which were eventually launched on December 18, 1999 and May 4,
2002 respectively. Both have far exceeded their planned 6 year mission life,
though the sensor data is poorer now than when new.
The image was taken by the satellite Terra on a south-bound pass, starting
at 11:44:19 and ending 11:58:37 UTC. What is shown below is a quick-look
generated at a fraction of the satellite's full resolution.
So it is kind of fitting that the first public image taken by the new DSS Ltd
should be from a satellite that the pedestal was originally built to service,
and given that satellite is now almost 21 years old it is able to buy us a
celebratory drink!
Today, 24 Jul 2020, DSS Ltd is one year old!
We are making progress on the new site and now have the equipment room
wired for 3-phase power and hope to have antennas on concrete plinths
within the next couple of weeks to allow for refurbishment and
testing. There are still many small jobs to sort out and various key
tasks have been delayed by the current pandemic, but we are seeing light
at the end of the tunnel.
This web site, and the bigger task of resurrecting what was
Scotland's only significant ground station, are still very much
"work in progress" so please be patient with us!
Background
Dundee Satellite Station Ltd was formed in July 2019 by two of the
former staff of the Dundee Satellite Receiving Station (DSRS) at the
University of Dundee when it was closed following the withdrawal of
NERC funding after over 40 years of operations.
The story behind this was covered well by The Register in these
articles:
Over
40 years of service axed for the sake of £338,000
Snatching
defeat from the jaws of victory
Jodrell
Bank goes full UNESCO while Dundee awaits the decomissioners
Also very well covered in
Spaceflight magazine Vol.61 No.6
Looking Forward
Subsequently we reached an agreement with the University to acquire
the assets of the receiving station with the intention to set up a
new site near Dundee to continue providing support to small
satellite operators and to the vast community of former users of
DSRS with the collection of Earth Observation data.
The former staff of the DSRS are deeply grateful to all of the
people and organisations that have supported us over the years. More
recently we are especially indebted to those who have contributed to
the GoFundMe campaign to
maintain public access to the Earth Observation data
as well as those who have provided time, advice, and letters of support that have
made any progress possible.
We are now making good progress towards our ambition of a new and
better facility. Our planning application for the new site was granted in
Feb 2020 and work started end of May 2020 (delayed by the COVID-19 lock-down).
We are also grateful for the professional support of Keir + Co in
the application process.
More recently we have some good news to report on
how the Dundee
Satellite Receiving Station might rise once more

About Us
Neil Lonie and Paul
Crawford worked at DSRS for 30 years prior to the creation of
Dundee Satellite Station Ltd and have considerable experience in the
design, construction, and operations of satellite ground stations.
Over that period we and our former colleagues built not just the
DSRS facility, but numerous other systems for other organisations world-wide
for environments as diverse as Antarctica (both British and Italian
Antarctic research facilities) thorough to Egypt (Food and Agriculture
Organisation project). In addition we have supported various
research and development projects for organisations such as
ESA, Eumetsat, NASA and NOAA.
An example of an Earth Observation image that we received at DSRS
(part of a larger image made famous by the newspaper coverage) is
shown here, with the centre of the image being roughly where the
new site is located:
