常见问题
•Do GNSS receivers work with GPS and other constellations, not only GLONASS?
Modern Russian GNSS equipment is multi-constellation by design, tracking GPS, GLONASS and typically Galileo and BeiDou as well. Using several systems simultaneously improves accuracy and reliability, especially in difficult terrain. Confirm the supported constellations and correction formats on the specific model's datasheet.
•Can antennas be tuned to the frequency plan of our country?
Yes. Cellular bands differ by market, and manufacturers produce antenna variants for specific frequency allocations or design custom elements for project quantities. Send your operators' band list (for example B3, B7, B20) and suppliers will match or adapt models accordingly.
•Are calibration certificates supplied with measurement antennas?
Measurement-grade horn and log-periodic antennas ship with factory calibration data, and accredited calibration with traceable certificates can be ordered additionally. State your laboratory's accreditation requirements when ordering so the documentation matches your quality system from day one.
•What is the minimum order quantity in this category?
Most antennas and receivers are sold from 1 unit, which suits pilot installations and lab purchases. Distribution pricing typically starts at 50 to 100 pieces for consumer-grade antennas. Because the goods are light, trial orders ship economically by international courier within about a week.
•What documentation accompanies radio equipment for customs and regulators?
Shipments include commercial documents, technical datasheets and EAC declarations where applicable. Radio transmitting equipment may require type approval in your country — receivers and passive antennas usually face no such requirement. Suppliers provide frequency and power specifications needed for your regulator's process.
