Install, integrate and verify, to signed acceptance.
We install, integrate and verify satellite ground systems on site. We run your test procedures and lead acceptance with you.
One accountable partner between your engineers and the site.
Decades of team experience integrating and testing LEO and GEO ground systems
Field teams put together for your regions, with clearances and capacity confirmed when we scope your program
Our team has deployed 100+ ground station gateways and 600+ secure GEO satellite endpoints. Our experience
The gap
Integration and acceptance compete for your engineers' time. We give it back.
01
Engineering time
Every trip to a remote gateway takes an engineer off the roadmap. New regions mean more trips.
02
Install is not acceptance
An installed site still has to be integrated, tested end to end and read against your criteria before anyone can sign.
03
Results need reading
Running a procedure is the easy part. Someone on site has to know what each output should be and see when it isn't.
Until those tests are run and read properly, an installed site can't be accepted.
Client outcomeEngineering time goes back to your roadmap.

Mission operations
Transition to operations. Ready for daily operation.
Before, during and after each site
Before the site
Before anything is built, we do the homework. We go through your test procedures, scripts and expected outputs with your engineers, then rehearse them in the lab before anyone travels.
On site
We run your procedures as written, record every result, help trace where an issue starts, and lead acceptance with you. Your engineers join on a call when an output needs a second look.
Back to your team
Results, logs and steps to reproduce go into your defect system. We review results with you daily during integration and send weekly status.
For mature operators, we work inside your framework and tools.
Any configuration change on site goes through your change control.
Full-stack integration
From the RF chain to your application
Between them, the engineers on site can follow a fault from RF through to your application without handing it off.
RF and antenna
G/T and EIRP, pointing and tracking, RF chain health, polarization and interference.
Optical terminals
Alignment, acquisition and tracking, atmospheric link characterization and laser safety.
Network and timing
Backhaul and routing, latency and jitter, path failover, GNSS timing and holdover.
Ground software
We run your application's test procedures and scheduling checks, and compare outputs with expected results.
Mission performance
Contact success, throughput, availability and recovery time, measured against your acceptance criteria.
Security when in scope
Hardening checks and access control, tested against your framework when the project calls for it.

Engagement models
Find the model that's right for you
Turnkey
We install, integrate and verify.
Best forNew networks and new regions, site by site.
Our crew installs to the SI&T plan, runs your test procedures and takes each site to signed acceptance, from the first site to the last.
Augment
Our specialists inside your team.
Best forOperators with a mature network and their own framework.
We add RF, network, application and performance engineers inside your framework and tools, at rollout peaks and as needed.
Team and skillsets: optimized on-site presence across every project phase
SI&T leadRuns the SI&T plan; leads acceptance to sign-off
Field engineersCivil, mounting, cabling, power-up to the SI&T plan

Cybersecurity test engineerChecks hardening and access control (if in scope)
Augment model: working side by side with your team. Clearance requirements and rollout capacity are confirmed when we scope the program.
Acceptance package
What you get for every site
One package per site, handed over at acceptance and signed by you.
Verification matrix
Pass or fail per requirement.
Test records
Subsystem test records and the end-to-end test report.
Defect log
Root cause and closure for each defect.
As-built records
Install drawings, inspection report and performance baselines.
Runbooks and SOPs
Handed to your operations team.
One format across your sites, or your template if you have one. Every requirement traced to a test record.
Next step
Start with your first sites
Bring the sites you plan to integrate first, and the procedures you'd want run on them.
Workshop with your engineers. Your priorities, requirements and acceptance criteria.
SI&T plan and proposal for the first sites, on the model that fits.
Crew mobilized. Each site installed, integrated and taken to your signed acceptance.
