Multi-band antenna system
UHF, VHF and S-band antennas on a single mast and shared rotor, with mast-mounted LNAs and precise tracking. L-band receive available on request.
UHF/VHF/S-Band Ground Station
A complete CubeSat ground station in one rack and one mast.
Modem, RF control and a tracked multi-band antenna, delivered as one tested system. You provide power, a network connection and a concrete pad. We deliver within 10 weeks of contract, then install, commission and train your operators on site.
Who it's for.
-
Universities and training centres
A real ground segment for CubeSat missions and hands-on operator training, not a lab simulation.
-
National space programmes and emerging space nations
Sovereign TT&C capability on your own soil, delivered with the training to run it.
-
Commercial and research satellite operators
A dedicated station for LEO missions, or extra capacity next to an existing network.
-
Mission rehearsal and testing
End-to-end checks of your ground segment before launch and during commissioning.
What's in the bundle.
Three modules that work together as one ground station. Each ships on its own or in any combination, and the turnkey bundle includes all three. Modem and Sequencer specs live on their own product pages. This page covers the station as a whole.
What turnkey means.
You get a working station, not a box of parts. Every turnkey delivery includes:
-
Site survey
Horizon mask, RF environment, power and network check, mast placement.
-
Factory integration
The full station is assembled and tested in Luleå before it ships.
-
Installation and commissioning
Our engineers install the rack and mast on site and track live satellites.
-
Acceptance testing
Agreed test passes, signed off with you.
-
Operator training
Hands-on sessions so your team runs passes independently from day one.
-
Support
1-year hardware warranty, plus software updates and remote support under an optional yearly support agreement.
How it fits together.
Every Remos ground station uses the same architecture, so a single-antenna site and a multi-band turnkey station are built from the same parts.

Antenna system
RF transmission & reception
Expedite is the modem and control unit. It generates and demodulates the TT&C signal and runs the pass schedule.
Sequencer sits in the RF path between modem and antennas. It routes each signal to the right band, switches the HPA and LNA in the correct order, and enforces TX/RX protection, so nothing ever transmits into an unprotected receiver.
Rotor control points the antennas and tracks each satellite across the sky.
The antenna system transmits and receives on UHF, VHF and S-band.
RF paths carry Tx and Rx between Expedite, the Sequencer and the antennas. Power and control lines drive the rotor. Every unit is also on your LAN or WAN over TCP/IP, so the whole station can be monitored and operated remotely, with live status, alarms and health data. It is built for unattended operation.
Deployed in the field.
One rack, one mast, one control system for multiple bands, missions and satellites.
All indoor equipment fits in one standard 19" rack: the rotor controller, Sequencer and Expedite, with a network switch on top. Outside, a single mast carries both UHF Yagis and the S-band dish on a shared rotor, with the LNA mounted at the mast to keep cable losses low. VHF and L-band receive are added per mission.
Proven in the field: Remos stations operate in Sweden, Tanzania, Ecuador, the UAE, Ireland, the USA, Spain and Germany, from 65°N in the Arctic to Tanzania near the equator.
Operate it from anywhere.
Run your station through Umoja, the Remos mission control and ground station network platform. Schedule passes, watch live telemetry and station health, and manage several sites from one browser window.
Want more coverage? Your station can join the Remos ground station network, which gives your satellites access to our sites and lets you offer spare capacity to other operators.
