GNSS Anti‑Jamming Products

Start with the integration requirement, not the largest number

Element count and channel count help engineers organise a first-pass comparison, but they do not prove that a product is suitable for a platform. A useful selection process begins with the receiver, the required constellations and frequency bands, the available mounting area, the RF and power interfaces, and the evidence the project team expects during evaluation.

ResiNav currently publishes anti-jamming terminals and independent anti-jamming and anti-spoofing product versions. The public catalogue records the parameters that can be compared without inference. Where a field is not published, treat it as an open engineering question rather than filling the gap from a similar model.

Compare the eight published configurations by signal, size, mass and power

Use the published product limits to make a first shortlist. The linked model records and English datasheets remain the sources for the full specifications. Elements and channels describe a configuration; they do not rank interference performance.

* The linked English datasheets state these power limits at normal temperature. † RN2511's English datasheet states ≤25 W without a temperature condition. Weight and size are product figures, not installed-assembly figures. A limit above your budget does not prove actual consumption or mass is above that budget; it means the public upper bound alone cannot establish compliance.

Open a linked model record for its full specifications and English datasheet. The existing Product Selection Guide download above the cards remains available for internal sharing.

See how a size and power limit changes the shortlist

Illustrative screen, not a project specification: suppose the required published signals are BDS B1 and GPS L1, the product body must fit within a 160 × 150 mm plan area, and the procurement record needs published upper bounds of 600 g and 15 W at normal temperature. Three ResiNav records document values within all four screens: RN-S65-4CH-SNB (65 × 65 mm; ≤130 g; ≤6 W), RN-009Pro-8CH-G1-WG-DT (150 × 130 mm; ≤400 g; ≤12 W), and RN2501-AJS-4CH-DPA (150 × 130 mm; ≤520 g; ≤13 W). These are documented first-screen candidates, not interchangeable or receiver-approved configurations.

This initial screen does not assess product height, mounting hardware, connector access or cable clearance.

If an anti-spoofing product version is required, RN2501 is the only one of those three published with that role. If GLONASS G1 must also appear in the public record, the G1 terminal documents it, but its public product role is anti-jamming only. The published records used here do not establish one option that meets both additional requirements; ask about the exact proposed configuration rather than inferring support or non-support from silence. A receiver match, installed mass, accessories and power outside the stated temperature condition remain separate decisions.

Ask ResiNav about the shortlisted model or your application. An estimated quantity and known requirements are enough to start; the existing detailed project brief can follow when a technical review is needed.

When to use the detailed project brief

Once a model is shortlisted, the GNSS anti-jamming RFQ checklist can help several teams align on the receiver, interfaces, installation and evaluation evidence. It is optional preparation for a later technical review, not a condition for first contact.

Use application context to refine the review

The same published product may face different installation and interface questions on a vehicle, vessel, robot or custom OEM platform. Review the relevant application guide before treating a catalogue match as a project recommendation.

• Vehicle and autonomous-system integration
• Engineering and mining vehicles
• Commercial marine and survey vessels
• Industrial robotics and automation
• Custom OEM GNSS integration

Questions for product selection

Does a higher element count automatically mean a better fit?

No. Element count is one architecture input. The required signals, receiver, interfaces, installation envelope, platform environment and evaluation criteria still need to be considered together.

Can two products with the same element count be treated as interchangeable?

No. Products in the same element-count group can differ in channel architecture, supported signals, mechanical dimensions, interfaces and product scope. Compare the current verified record for each model.

What if a required specification is not shown in the public catalogue?

List it as an open item and request the applicable documentation. Do not infer an unpublished value from another model or from a third-party listing.

Can I contact ResiNav before choosing a model?

Yes. Share the model or application you are considering, an estimated quantity and any requirements already known. The model and technical details can be discussed later.

Ask about a product or application

Tell ResiNav what you are considering and what you already know. A model is helpful but not required; detailed configuration questions can follow the first exchange.
