A passive, full-spectrum precision antenna for demanding phase-tracking, survey, reference network, marine and machine-control applications.
VeraPhaseâ„¢
A high-performance geodetic GNSS antenna for systems where phase-centre stability, multipath rejection and repeatable carrier-phase measurements matter.
Smart antenna-receivers
An antenna and u-blox ZED-X20P receiver in one rugged unit for high-precision RTK, PPP-RTK, autonomy, fleet and rapid product integration.
Anti-jamming technology
A resilient PNT antenna combining low-elevation nulling with high-rejection filtering for interference-prone timing and critical-infrastructure sites.
Selection guide
The correct GPS or GNSS antenna depends on the receiver, frequency plan, mounting method, cable length, RF environment and positioning or timing accuracy you need to protect.
Prioritise tight phase-centre behaviour, full-band tracking and L-band correction support for CORS, RTK and geodetic work.
VSP6000P · VP6150
Keep size and weight low while maintaining multi-band tracking and resistance to reflected satellite signals.
HC977SXF
Combine the antenna and GNSS receiver to shorten the RF path and simplify a precision product design.
TW5398
Reduce low-elevation interference around GPS timing sites and positioning infrastructure where continuity matters.

Frequently asked questions
These are the first questions AMS Extreme uses to narrow the right GNSS antenna for a Malaysian project.
A GPS antenna receives the US GPS constellation. A multi-constellation GNSS antenna can also receive Galileo, GLONASS, BeiDou, QZSS and NavIC signals, depending on its supported bands.
The choice depends on the timing receiver, supported bands, cable length, gain, mounting location, surge protection and local RF environment. TW3885TL is one dual-band timing-focused option.
Look for stable phase-centre behaviour, low multipath sensitivity and the required full-band or L-band correction support. VSP6000P and VP6150 are relevant precision families.
AMS Extreme can help specify Calian resilient PNT options including AJ977XF+, based on constellation coverage, interference direction, filtering and installation requirements.
