They are also used to navigate back to these locations. These instructions detail how to use the GPS in normal conditions and more challenging situations and also how to use the software in the lab to download, upload and convert data. When using the Trimble XRS Pro GPS with the Omnistar real-time correction service, we can expect submeter accuracy (+ 70 cm or better). Data Managerhttp://lter.kbs.msu.edu/protocols/49The LTER GPS units are used for recording the locations of microplots, experiments, instrumentation, plot corners, sampling sites, events and many other LTER features. They are also used to navigate back to these locations and to navigate to new locations whose coordinates have been uploaded to the GPS. When using the Trimble XRS Pro GPS with the Omnistar real-time correction service or the internal Coast Guard beacon we can expect submeter accuracy (approximately + 20 to +70). We keep the Omnistar real-time correction service on the GPS I data logger and the Coast Guard beacon on GPS II. We can always start the Omnistar service on GPS II if needed for $400/year. We switched to the Coast Guard beacon from 25 June 2008- 3 August 2009 but we went back to the Omnistar service because the connection to the Coast Guard beacon wasn’t dependable . We are in a weak spot for the beacon and also in high humidity conditions it is more difficult to receive the signal. When we were able to get the connection the resolution was similar (5 cm – 30cm less accurate than Omnistar during the testing periods).Data Managerhttp://lter.kbs.msu.edu/protocols/106https://lter.kbs.msu.edu/datatables/149Kellogg Biological Station LTER: Narrative Agronomic Field Log (KBS058-001)Log of the agronomic activities on the GLBRC Intensive siteNarative+Agronomic+Field+Log.csvNone211\ncolumn,no"\https://lter.kbs.msu.edu/datatables/149.csvobs_datedate the activity was doneYYYY-MM-DD11987-4-18commentdescription of the activitydescription of the activityhttps://lter.kbs.msu.edu/datatables/178Kellogg Biological Station LTER: GLBRC Agricultural Materials Record (KBS058-004)A record of the Materials applied to the GLBRC main site units are per acre.
