A satellite move comes through, and the new one runs a different polarization than the last. In a lot of teleports, that still means what it's always meant: someone drives out, gets up on the antenna deck or the feed boom, throws the switch by hand, and drives back, hoping nothing else needs attention before the next pass. If the site is unattended, it means someone books a flight instead.
That workflow has stuck around less because it's inefficient and more because the obvious fix, remote polarization control, has usually meant replacing the feed or the switch hardware to get it. The Radeus Labs RL250 was built to remove that trade-off. It brings remotely commanded, feedback-verified CP/LP selection to the switch hardware already sitting on the feed, so a polarization change becomes a command from the NOC instead of a truck roll, and the NOC knows the switch actually moved instead of guessing.
Integrated into the site's antenna-control and monitoring environment over TCP/IP Ethernet, it uses CP and LP switch indicator contacts to report the current switch state to the control system, giving operators positive state feedback rather than relying only on the command issued.
What it delivers:
For compatible existing installations: no feed replacement, no new switch hardware, just a remotely commanded polarization change instead of a site visit.
Here are several SATCOM environments where remote, feedback-verified polarization control delivers the greatest operational value.
Move an antenna from a satellite using linear polarization (common in C- and Ku-band FSS) to one using circular polarization, and the feed's polarization switch has to be thrown. Without remote control, that's a technician driving to the site, sometimes an antenna-access task in its own right. With the RL250, it's a command from the NOC: repolarize the feed remotely from the operations center, without a truck roll or field dispatch.
Arctic sites. Desert sites. Offshore platforms and diversity sites running with nobody on the ground. At unattended sites, a command acknowledgement alone isn't enough: the NOC needs confirmation that the switch reached the commanded state. The RL250 accepts CP and LP switch-indicator feedback for each channel and reports the current switch state to the control environment, giving the NOC a confirmed operating state before proceeding with the next step in the workflow. When the nearest human is hours away, that distinction matters.
Deployed terminals routinely shift between military circularly-polarized payloads and leased commercial linearly-polarized capacity as missions and bandwidth availability change. With two independent channels in a single box, one RL250 can support both feeds of a dual-feed or Tx/Rx-split terminal. It addresses feed-polarization control within the broader terminal reconfiguration workflow as operators move between circularly polarized military services and linearly polarized commercial capacity.
Ad-hoc space segment bookings land on whatever satellite has capacity, and polarization varies by satellite and transponder. For crews using coordinated lineup procedures, RL250 polarization selection can be incorporated alongside antenna pointing and other pre-transmission checks, one less manual task standing between the crew and air.
Stations supporting many spacecraft a day (GSaaS networks, LEOP support, academic and NASA-affiliated ground stations) need per-pass reconfiguration on a schedule, not a staffing plan. Where the site's ACU and M&C platform support scheduled command sequences, the RL250 can add polarization configuration to the per-pass workflow.
Building a new terminal or modernizing a legacy one, integrators get a drop-in 1RU box that works with the standard and latching polarization switch motors already sitting on the feed. No feed replacement required. It's a way to bring IP control to antennas that have never had it, without touching the parts that already work.
A few things are true across every use case above:
The best way to know if the RL250 fits your site is to talk it through with someone who's dealt with polarization switching in the field. Reach out to Oliver Burns, SATCOM Specialist at Radeus Labs to walk through your specific feed, switch circuit, and remote control needs.
