For antenna types listed in the antennas.xml database file, Trimble 4D Control Server lets you provide individual calibrations so that information from special calibrations can be used for processing. All you have to do is provide your location below and submit. If you deviate from the selected measurement method, you will have to manually correct the antenna height. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Nevertheless, Trimble recommends backing up your individually created files. To correct to the antenna reference point (ARP) which is what RINEX expects, you then have to subtract the "bottom of antenna mount"correction from the APC: The RINEX converter assumes that the antenna height was measured in the defined way. endstream endobj 27 0 obj <1\\dW, )/V 2>> endobj 28 0 obj )/Name(^^8N-#`&!\rT)/Prop_Build<>/Filter<>/PubSec<>>>/Reference[<>/Type/SigRef>>]/SubFilter/adbe.pkcs7.detached/Type/Sig>>>>/Type/Catalog/ViewerPreferences<>>> endobj 29 0 obj <> endobj 30 0 obj <>/Font<>>>/Fields 19 0 R/SigFlags 2>> endobj 31 0 obj <>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 32 0 obj [33 0 R 34 0 R 35 0 R 36 0 R 37 0 R 38 0 R 39 0 R 40 0 R] endobj 33 0 obj <>stream The GNSS receiver reduces all of the measurements at the L1 and L2 Antenna Phase Centers to the Mechanical Antenna Phase Center. 0000014905 00000 n A helix based, dual-frequency antenna ideal for UAV applications due to its lightweight, small form factor and low power consumption design.
