RN2501-AJS-4CH-DPA
4-Element GNSS Anti-Jamming and Anti-Spoofing Terminal
A GNSS anti-jamming and anti-spoofing product version with 4 antenna elements and 4 channels; the public record lists BDS B1 and GPS L1. Download the English datasheet, review the specifications or ask about this model.
Documentation: Public datasheet available
PRODUCT OVERVIEW
System role and selection context.
This independent anti-jamming and anti-spoofing product version is designed for receiver and platform integration. Engineering review should consider the required signal configuration, system interface, available installation space and the integration constraints of the target navigation architecture.
Multi-Frequency Configuration
The verified product record supports evaluation across more than one documented frequency band.
Channel Architecture
A verified channel configuration is available for receiver and system architecture review.
Array Configuration
A verified antenna-element configuration provides a clear basis for comparing models in the series.
Anti-Spoofing Product Version
Independent anti-jamming and anti-spoofing product version. Final configuration is subject to engineering review.
ENGINEERING OVERVIEW
Documented configuration for integration review.
The published RN2501 record identifies BeiDou B1 and GPS L1 in a 4-element, 4-channel configuration. Use the dynamic specification panel for the complete published product values; then review the intended PVT connection, mounting and test evidence for the installation. An anti-spoofing product label does not establish a platform-level result or certification.
SELECTION GUIDANCE
Confirm the documented fit before requesting a quote.
Compare the documented signal set and array with the platform's position-data requirements. The numbers support a shortlist; mounting, power, interface and threat-scenario evidence remain separate selection inputs.
BUYER COMPARISON
Separate a published fact from a project decision.
| Decision input | Published RN2501 fact | Confirm for your project |
|---|---|---|
| Signal set | BeiDou B1 and GPS L1 | Required signals and intended use of the HDMI PVT output |
| Array and channels | 4 elements; 4 channels | Applicable evidence for the intended interference scenario |
| Physical envelope | 150 × 130 × 22 mm; weight ≤520 g | Mounting drawing, clearance, orientation and cable route |
| Power and RF output | ≤13 W at normal temperature; 50 Ω RF output impedance | Power supply, connector access and any planned use of the published RF output |
| Anti-spoofing version | Independent anti-jamming and anti-spoofing product version | Threat model, applicable test evidence and platform response |
