Tiantong terminals, BeiDou short messages, satellite earth stations, RTK high precision — RF metrics, spurious emissions and antenna gain directly decide whether type approval is granted; earth station and radio station licences are administrative paths outside certification and must be planned early.

Scope covers satellite communication terminals (Tiantong satellite phones, BeiDou short-message terminals, shipborne, airborne and vehicle satellite stations), satellite earth station equipment, BeiDou positioning terminals (vehicle, handheld, wearable, timing), GNSS and RTK high-precision receivers and modules, satellite antennas and RF front ends. BeiDou B1/B2/B3 is compatible with GPS, GLONASS and Galileo, with Tiantong and LEO links, short-message communication, high-precision RTK solving, anti-jamming and low-elevation acquisition.
What we do: satellite terminal type approval and earth station licensing filing, BeiDou-only mode verification and documentation, RF link and antenna performance pre-testing, spurious and anti-jamming rectification, and difference statements for series model extensions.
Broken down by product form, so you can see at a glance which certificates and test items apply:
| Sub-category | Typical products & technical features | Core compliance items | Special & value-added |
|---|---|---|---|
| Satellite communication terminals | Tiantong satellite phones, BeiDou short-message terminals, satellite earth stations | SRRC type approval; earth station licensing and radio station licence; CTA (when connecting to the public network) | Satellite link performance; antenna gain and EIRP; support for licensing tests |
| BeiDou positioning | Vehicle, handheld and wearable positioning terminals; multi-constellation GNSS | SRRC; BeiDou-only special testing | Positioning accuracy and cold-start time; timing accuracy; power consumption |
| High precision | RTK receivers, GNSS modules, satellite antennas | SRRC; CCC determined by device form | Multi-constellation compatibility; multipath and interference resistance; baseline solving verification |
“Core compliance items” are what regulations or industry access require; “special & value-added” items are supplementary work that strengthens competitiveness in tenders, central procurement and channel access. The table shows common cases; in practice each item is verified against the product function list and the current catalog.
All of these have caused rework in real projects — avoiding them early saves 2–4 weeks:
Formal testing takes place at designated laboratories; before submission we run baseline checks in our own RF anechoic chamber and EMC lab, so fixable issues are solved in-house.

Pre-testing is not a formality. In projects on this line, spurious emissions, harmonics and EMC account for most rework, and 3–5 days of baseline testing up front often saves a whole round of laboratory queuing.
We review the datasheet, antenna documents and network topology, then issue a written determination: which certificates are needed and whether units can be combined.
Baseline runs in the anechoic chamber and EMC lab; over-limit items are fixed first, avoiding a queued formal test that gets returned.
Samples go out per the designated laboratory's schedule; we track progress and rectify non-conforming items.
Document submission, formal review, certificate issuance and marking instructions — each milestone is shared with the project owner.
Overall reference timeline 10–18 weeks, compressible with parallel filing; structural changes or retests extend it accordingly. Fees are quoted item by item according to certification scope and number of models; reference ranges are subject to our written assessment.
