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/106programNational Science Foundationhttp://dx.doi.org/10.13039/100000001DEB 2224712https%3A%2F%2Fnsf.gov%2Fawardsearch%2FshowAward%3FAWD_ID%3D2224712%26HistoricalAwards%3Dfalsehttps://lter.kbs.msu.edu/datatables/83Kellogg Biological Station LTER: GPS Coordinates of All LTER and GLBRC Features (KBS039-002)GPS coordinates for many LTER and GLBRC point features such as plot corners, sampling stations, lysimeters, etc.GPS+Cordinates+of+Al+LTER+and+GLBRC+Features.csvNone331\ncolumn,no"\https://lter.kbs.msu.edu/datatables/83.csvstart_datedate when the location was first usedYYYY-MM-DD11987-4-18end_datelast date the location was usedYYYY-MM-DD11987-4-18sitelocation where the experiment is locatedlocation where the experiment is locatedexperimentLTER or GLBRC experimentLTER or GLBRC experimentcommentcommentcommenttreatmentKBS treatment codeKBS treatment codereplicateKBS replicate codeKBS replicate codestationsampling locationsampling locationfeaturetype of experimental activity at this locationtype of experimental activity at this locationlongitudX coordinate in SRID 4326reallatitudeY coordinate in SRID 4326realgps_datedate the GPS reading was madeYYYY-MM-DD11987-4-18gps_corrtype of correction applied to the datatype of correction applied to the datagps_typetype of GPS unit type of GPS unit https://lter.kbs.msu.edu/datatables/84Kellogg Biological Station LTER: GPS Coordinates (Expanded) (KBS039-003)Additional fields given for GPS coordinates such as PDOP.GPS+Cordinates+(Expanded).csvNone411\ncolumn,no"\https://lter.kbs.msu.edu/datatables/84.csvTreatmentKBS LTER treatment codeKBS LTER treatment codeReplicateKBS LTER replicate codeKBS LTER replicate codeFeature NameThe type of featureThe type of featurePlotTreatment and Replicate combined in one fieldTreatment and Replicate combined in one fieldFeatureDescriptionSpecific information about the featureSpecific information about the featureMicroplotA microplot name if applicableA microplot name if applicableGPS_DateThe date the point was recordedYYYY-MM-DD11987-4-18NorthingZone 16N UTM reference of point (NAD_1983_UTM_Zone_16N)meterrealEastingZone 16N UTM reference of point (NAD_1983_UTM_Zone_16N)meterrealNumberOfPointsThe number of points averaged to make up the current pointdimensionlessintegerCorrectionTypeThe type of correction applied to the data (realtime, postprocessed or uncorrected)The type of correction applied to the data (realtime, postprocessed or uncorrected)Max_PDOPThe Maximum PDOP encountered while recording this pointdimensionlessrealMax_HDOPThe Maximum HDOP encountered while recording this pointdimensionlessrealReceiverTypeThe Name of the GPS receiver usedThe Name of the GPS receiver usedUpdate_StatusWhether the point is new or updated (Trimble info)Whether the point is new or updated (Trimble info)DatafileThe original Trimble data filenameThe original Trimble data filenameDataDictionaryThe name of the data dictionary used while recording the pointThe name of the data dictionary used while recording the pointGPS_HeightThe height of the point above mean sea levelmeterrealVerticalPrecisionOne standard deviation around the vertical positionmeterrealHorizontalPrecisionOne standard deviation around the horizontal positionmeterrealStandardDeviationStandard deviation in all directions of the pointmeterrealCommentCommentCommenthttps://lter.kbs.msu.edu/datatables/152Kellogg Biological Station LTER: KBS LTER Survey Monument Coordinates (KBS039-004)Locations of 2 LTER survey monuments that were set in 2006 by Jensen Land Surveying (Richland, MI.) using 2 survey grade Ashtec Promark 2 GPS units.
