High-Precision Measurement
High-Precision GNSS Measurement Antennas
GNSS measurement antennas for surveying, deformation monitoring and reference stations, with built-in platforms for precision agriculture and marine-survey equipment. Choose by exact signal coverage, receiver interface and installation conditions.
Application Overview
Choose the Antenna for Your Measurement System
Select an antenna by the receiver's enabled GNSS signals, phase-center requirement, interface and installation. A phase-center specification describes the antenna; it does not guarantee the positioning accuracy of a complete RTK or monitoring system.
The external TDXL-BA1500 serves surveying, deformation monitoring and reference-station installations. The built-in TDXL-BA700 is an option for geodetic and marine surveying, precision agriculture and monitoring equipment.
Review built-in versus external installation and active versus passive reception separately. Active models need a compatible antenna supply and a cable-loss budget; passive platforms require receiver-chain review. Environmental ratings, calibration evidence and mounting details must be checked for the specific model and configuration.
Selection & Integration Checks
Phase-center specification
Separate antenna parameters from whole-system accuracy.
Signal coverage
Match the exact signals, not just constellation names.
Receiver & cable
Check active/passive type, supply, interface and cable loss.
Mechanical integration
Review enclosure, mounting drawing and cable routing.
Environmental evidence
Confirm model-specific IP ratings and available test reports.

FAQ
Measurement Antenna FAQs
Common procurement and integration questions for geodetic survey, RTK, and CORS applications.
Does phase-center stability mean the same positioning accuracy for the entire system?
No. BA1500 has a phase-center error specification of ±2 mm; this is an antenna parameter. System positioning performance also depends on the receiver, corrections, installation and multipath. Include any network calibration requirements in your inquiry.
Which GNSS signals do BA1500 and BA700 support?
BA1500 and BA700 support BDS B1I/B1C/B2a/B2b/B3I, GPS L1/L2/L5, GLONASS G1/G2 and Galileo E1/E5a/E5b. Compare the exact model signal coverage with your receiver’s enabled signals.
How should I select LNA gain and cable length?
TDXL-BA1500 specifies 40±2 dB LNA gain and a noise figure of ≤2.0 dB. These values alone do not determine an allowable cable length. Provide the cable type, length, connector losses, receiver gain limits and antenna supply requirements so the complete RF and power budget can be reviewed.
Can BA700 be used for an embedded OEM integration?
BA700 is a built-in GNSS antenna for geodetic and marine surveying, precision agriculture and deformation-monitoring equipment. Send your receiver model, enclosure, mounting drawing, cable requirements and quantity for an integration quote.
Are all measurement antennas IP67 rated?
No. Protection requirements are model- and installation-specific. Include outdoor exposure, connector sealing and enclosure requirements when selecting an antenna.
What should I provide for a BA1500 quotation or receiver compatibility check?
Provide the receiver model, required GNSS signals, cable route and length, mounting drawing, environment and quantity. BA1500 specifies a TNC-K interface, 3–12 VDC supply and ≤45 mA current; verify compatibility with the receiver's antenna power output. Confirm the supplied dimensional drawing and any adapters. MOQ, availability and lead time are quoted for the agreed configuration.
