Arcturn Defense Solutions

Ground systems, known from the inside.

Arcturn is built on time spent operating, maintaining, installing and engineering satellite ground systems. That shapes everything the firm does: analysis that matches how stations actually behave, tools built around the work they support, and training aimed at operating and maintaining a system well enough to extend its service life.

Capabilities

What the firm does

Work that leaves a customer more capable of understanding and sustaining their own systems.

01

Software tools

Tools built to a stated need, for the cases general-purpose software handles badly. The point is to widen what an operator can see in their own system, so the understanding stays in house rather than with a vendor. Browser-based where the data is sensitive, so records are parsed locally.

02

Operator and maintainer training

Instruction for the people who run, maintain and install ground-segment equipment, written by someone who understands what it takes to operate and maintain ground systems effectively, with the goal of extending the service life of the system.

03

Systems engineering and analysis

Consulting systems engineering and ground-system analysis for problems in the RF chain. Turning the telemetry a station already produces into evidence: drive degradation, tracking-error signatures, signal margin, and faults that resist a straightforward reading.

Work

Current work

Software built and maintained directly.

Ground-segment analytics

Sentinel Pass Analyzer

A browser-based analyzer for satellite-antenna pass reports. Pass data is parsed entirely in the browser rather than uploaded for processing. It reads the records an antenna control unit already writes and returns servo and signal analysis, fault and interlock timelines, dropout forensics, and diagnostics that name the likely mechanism rather than just flagging an anomaly.

Batch analysis aggregates hundreds of passes into sky-coverage heatmaps, torque profiles and trend series, so a slow mechanical drift becomes visible long before it becomes a failure.

The analyzer follows a modular open systems approach and is vendor agnostic. Record formats sit behind a common interface rather than inside the core, so bringing an unfamiliar system in needs one example pass to build an analysis harness against, not a rewrite.

Three panels of analysis output: a sky-coverage plot showing a pass tracked from the
                      north-east horizon through high elevation, with a short segment marked as a dropout;
                      a drive-torque trace with a highlighted window of elevated variance; and a timeline of
                      events. All values are simulated.

Training

Teaching the system, not the manual

Instruction for the people who keep a station on the air, aimed at the service life of the equipment rather than the length of the course.

Operations

Running passes with an understanding of what the antenna is actually doing. Track modes and when each one is appropriate, acquisition and handover, reading signal behaviour as it happens, and telling a genuine equipment fault from weather, geometry or a bad ephemeris.

Maintenance

Keeping drives, encoders and the RF chain healthy, and catching degradation while it is still a maintenance item rather than an outage. Inspection routine, what wear looks like in telemetry before it is audible, fault and interlock interpretation, and the difference between a symptom and a cause.

Installation and commissioning

Taking a system from delivered to trusted. Siting and alignment, cable and waveguide practice, pointing and boresight verification, and commissioning measurements that establish the baseline every later comparison depends on.

Course material is written against the customer's own equipment, and where it helps, their own pass records, so the examples are systems the room already recognises. Delivered on site or remotely, and scoped to the crew rather than to a fixed syllabus.

About

The firm

Arcturn Defense Solutions is a North Carolina limited liability company working in satellite ground systems.

Its founder has worked the ground segment as an operator, a maintainer, an installer and an engineer. The tools and the training come directly out of that experience, built by someone who has sat in the same chairs as the people who will use them.

Arcturn is small and veteran operated, and intends to stay small enough that customers deal directly with the person doing the work. The aim is a long professional relationship built face to face, rather than an account passed down a chain.

Engagement

How work starts

Small enough that the first conversation is with the person who will do the work.

01

A conversation

Describe the problem. Often one call is enough to establish whether it is worth engaging on at all, and saying so plainly is more useful than a proposal for work that will not help.

02

A scoped piece of work

An agreed deliverable with a defined boundary: an analysis of a specific problem, a tool built to a stated need, or training for a named group. Scope set before the work starts, not discovered during it.

03

Something you keep

The output is yours: the findings, the tool, the course material, and the understanding behind them. The measure of a good engagement is that it leaves less need for the next one.
