With its advanced multi-band RF front-end, the UM982 ultraLight Smart Antennas set is capable of simultaneously tracking all four major GNSS constellations — GPS, GLONASS, Galileo, and BeiDou — ensuring robust positioning, heading and centimeter-level accuracy when combined with correction data.\u003c\/p\u003e\n\u003cp data-start=\"1429\" data-end=\"1693\"\u003eThe built-in multi-frequency anti-jamming technology enhances RTK calculation on multiple modes and frequencies, which significantly improves RTK initialization time, measurement accuracy and reliability in complex environments such as city blocks and tree shades.\u003c\/p\u003e\n\u003cp data-start=\"1695\" data-end=\"2218\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eWith its dual-antenna input, the UM982 can deliver compass-free yaw information to the controller (commonly referred to as GPS Heading or Moving Baseline Yaw). By using GPS as the yaw reference instead of a traditional compass, it eliminates errors caused by magnetic interference from vehicle motors, electrical systems, or external sources such as metallic structures and power lines. This ensures accurate yaw data for the controller and improves navigation reliability and performance, even in challenging environments.\u003c\/p\u003e\n\u003ch6\u003e\u003cstrong\u003eDevice Features:\u003c\/strong\u003e\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eBased on NebulasIV GNSS SoC with integrated RF, base band, and high precision algorithm\u003c\/li\u003e\n\u003cli\u003eTwo optional UART\u003c\/li\u003e\n\u003cli\u003eSupports robust high-precision positioning via RTK, PPP, and Galileo HAS correction services.\u003c\/li\u003e\n\u003cli\u003eAll-system multi-frequency RTK engine and advanced RTK technology\u003c\/li\u003e\n\u003cli\u003eIndependent tracking of different frequencies and 60dB narrow band anti-jamming technology\u003c\/li\u003e\n\u003cli\u003eLow Noise Amplifier (LNA) integrated with the compact helical antenna\u003c\/li\u003e\n\u003cli\u003eHigh Gain: 28 dB typ. from antenna\u003c\/li\u003e\n\u003cli\u003eAxial ratio: 3 dB max.\u003c\/li\u003e\n\u003cli\u003eTight Phase Center Variation (PCV)\u003c\/li\u003e\n\u003cli\u003ePower supply: 5 VDC\u003c\/li\u003e\n\u003cli\u003eIntegrated 3-axis digital compass sensor RM3100 for accurate heading and orientation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003e\u003cstrong\u003ePhysical Characteristics:\u003c\/strong\u003e\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eDimension: Ø50x41 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 34 g\u003c\/li\u003e\n\u003cli\u003eWater and Dust Resistance: IP55\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -10 °C ~ +60 °C\u003c\/li\u003e\n\u003cli\u003eConnector type: JST SH 6 pin, JST GH 6 pin, SMA\u003c\/li\u003e\n\u003cli\u003eMounting Options: Waterproof 3M double-sided tape, Screw mount\u003c\/li\u003e\n\u003cli\u003eRoHS \u0026amp; Reach Compliant\u003c\/li\u003e\n\u003cli\u003eFully assembled, tested, sealed, and ready for use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003e\u003cstrong\u003ePackage contents:\u003c\/strong\u003e\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eSmart antenna – 1 pс\u003c\/li\u003e\n\u003cli\u003eHelix antenna \u003ca href=\"https:\/\/gnss.store\/products\/elt0244\"\u003eELT0244\u003c\/a\u003e with cable 1 m - 1 pc\u003c\/li\u003e\n\u003cli\u003eCable \u003ca href=\"https:\/\/gnss.store\/products\/elt0480\" target=\"_blank\" rel=\"noopener\"\u003eELT0480\u003c\/a\u003e JST GH male 6 pin to 6 pin compatible with Pixhawk, 0.2 m – 1 pc\u003c\/li\u003e\n\u003cli\u003eCable \u003ca href=\"https:\/\/gnss.store\/products\/elt0486\" target=\"_blank\" rel=\"noopener\"\u003eELT0486\u003c\/a\u003e 1 m SMA M to SMA F - 1 pс\u003c\/li\u003e\n\u003cli\u003eWaterproof 3M double-sided tape – 2 pс\u003c\/li\u003e\n\u003cli\u003eScrews 2.5x6 – 6 pс\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELTEHS","offers":[{"title":"1UART","offer_id":57331235062092,"sku":"ELT0218-1U","price":354.99,"currency_code":"EUR","in_stock":true},{"title":"3UART","offer_id":57331235094860,"sku":"ELT0218-3U","price":354.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/6262\/0236\/files\/um982-ultralight-heading-rtk-gnss-smart-antenna-set-8901850.jpg?v=1792434862","url":"https:\/\/gnss.store\/products\/elt0218","provider":"GNSS Store","version":"1.0","type":"link"}
