b m o c gps basics by monica spicker ۲ ۱ some figures are copyrighted and used with the kind permission of dr. peter h. dana. b m o c objectives student will understand how gps basically works understand the limitations of gps describe common error sources correctly setup a receiver input waypoints in the classroom and in the field navigate to points in the field using a variety of techniques. b m o c b m o c b m o c rule to remember a gps receiver is an accessory not a replacement for a map compass altimeter and good basic navigation skills b m o c b m o c parts of a gps system b m o c b m o c satellites ۶ orbital planes ensure at least ۴ or more satellites available at almost all times. there is a large gap to the north. about ۳۱ satellites very high orbits several replaced every year. b m o c b m o c receiver ۱ – ۵ ۱ meter accuracy computer cable download and upload maps routes and waypoint. upgrade over the internet computer mapping software can map out tracks and waypoints can plan and upload routes tracks and waypoints receivers may also have digital compasses barometric altimeters frs radio other features. b m o c b m o c hints check batteries and settings before setting out. use lithium batteries when available. practice with and know all needed screens on your receiver. have all your screens set the way you want them if possible set up trip screen to include both utm and latitude longitude fields. clear out old tracks unneeded waypoints. organize waypoints by name and symbol for easier management. calibrate the compass and altimeter if you have them. have all navigation equipment together and readily available. tie your navigation equipment onto yourself. b m o c b m o c three okay four or more better ۳ satellites are needed to acquire a position fix. ۲d mode ۴ satellites are needed for an accurate position and to get elevation. ۳d mode more satellites are really needed because of errors that arise from a variety of sources. satellite positions geometry weather multipath timing errors typical error is ۱ meters. all gps are ۱۲ channel can receive up to ۱۲ satellites b m o c ideal satellite geometry n s w e poor satellite geometry n s w e b m o c gps cannot see through objects some of the newer satellites and receivers can receive through thinner solid objects like cars building walls and forest canopy. terrain and larger buildings are still too big. b m o c b m o c a signal that bounces of a smooth object and hits the receiver antenna. increases the length of time for a signal to reach the receiver. a big position error results. gravel roads open water snow fields rock walls buidlings multipath error b m o c b m o c initializing the receiver setup critical map datum grid system it is possible to create your own grid and or datum distance units other features or options if you have a digital compass set it to kick in at under ۲ mph speed calibrate compass and altimeter if receiver has them. b m o c b m o c map datums earth model to reference and compute coordinates gps based on world geodetic system ۱۹۸۴ wgs ۸۴ usgs quad maps based on north american datum ۱۹۲۷ nad۲۷ some us maps are based on nad۸۳ wgs۸۴ canadian maps are based on nad۸۳ other countries have their own datums gps receiver set up must match map. b m o c b m o c what happens when datum is not set correctly b m o c b m o c elevations gps uses height above ellipsoid hae elevations on a map are based on mean sea level shape hag can be very different and you won’t know where or when it’s different and by how much. satellite geometry error increases elevation error. do not use gps elevations for critical navigation decisions. gps receivers with barometric altimeter use both methods. set to fixed barometric altimeters still need to be regularly calibrated at a known elevation. b m o c b m o c waas wide area augmentation system ۲۵ ground reference stations in us monitor gps satellite data and calculate corrections. the correction is broadcast through one of two geostationary satellites. currently waas coverage is only in us and parts of southern canada. any receiver with a waas antenna can receive the signal. must enabled through setup. uses up batteries doesn’t always give best results. uses up to ۴ regular satellite channels. b m o c what receivers record track logs collected any time receiver is on. should be cleared before each mission overwrites previous positions if track memory is full tracks track logs can be saved for reuse not as much detail as log can be drawn on computer map and uploaded waypoints stored or entered locations routes set series of waypoints less detail than a track b m o c b m o c b m o c navigation need to have stored waypoints. travel is in a straight line from waypoint to waypoint route . can also be a track you uploaded and follow. feedback is distance and direction – compass and pace may be more efficient. can use to check progress and whether you are still on track. can save waypoints along the way and follow back reverse route . straight line may not be safest use a map when planning or to double check b m o c planning a navigation route start waypoint receiver downloads new position every ۵ to ۳ seconds. compass may jump best to follow hand compass or electronic compass rather than gps compass. if receiver has electronic compass set it so it will kick in at under ۲ mph. as long as distance is decreasing you are going the right direction. can select easier terrain to increase travel …
