The LTER GPS units are used for recording the locations of microplots, experiments,instrumentation, plot corners, sampling sites, events and many other LTER features that need to be mapped in the LTER GIS.
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). Trimble XRS Pro GPS Instructions for the LTER LaboratoryData 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).GPS Protocol for the LTER LaboratoryData Managerhttp://lter.kbs.msu.edu/protocols/106https://lter.kbs.msu.edu/datatables/273Kellogg Biological Station LTER: Activity Report (GLBRC083-003)This tables lists the activities and equipment used on replicate 1 of the GLBRC BCSE (Biofuel Cropping System Experiment).

Field 98-1 (5.8 acres) is approximately the field area west of the GLBRC Biofuel Cropping System Experiment, field 98-2 (23.4 acres) is approximately the northern section of the GLBRC Biofuel Cropping System Experiment where blocks 1-3 are located and field 98-3 (26 acres) is approximately the southern section of the GLBRC Biofuel Cropping System Experiment where blocks 4-5 are located.
Prior to 1988, field 98 was managed by the KBS Dairy Farm. Crop rotations or rotation duration for specific years prior to 1988 can not be identified. With relative confidence we can say that the crops produced prior to 1988 consisted of four types: alfalfa, corn, soybeans, and wheat. By verbal communication from KBS Dairy Farm members KBS has owned/managed field 98 in 1980 and most likely as far back as the 1950’s-1960.KBS+GLBRC+Intensive+Site+Crop+History.csvNone231\ncolumn,no"\https://data.sustainability.glbrc.org/datatables/412.csvyearcrop yearYYYY11987-4-18field_idField identifier used prior to the GLBRC project.
