Introduction 1 Introduction 1 Intr oduction What is the Pr oMark2 Survey System? ProMark2 is a complete GPS system providin g both navigation an d precision surveying.
2 Promark2 User’ s Guide The ProMark2 System operates in conjunction with Ashtech Solutions, Thales Navigation’ s highly-automated GPS post-processing engine.
Introduction 3 Introduction External GPS Antenna The external GPS antenna, Figure 1.3, is required for surveying functions. While the built -in antenna is sufficient for navigation, a more sophisticated ex ternal antenna is required to obtain quality data for precisio n survey ing.
4 Promark2 User’ s Guide V ertical Antenna Extension The vertical antenna extension, Figure 1.5, provides clearance for the antenna cable when the antenna is mounted on a tripod. The length is 3 inches (0 .0762 m). Field Receiver Bracket The field receiver bracket, Figure 1.
Introduction 5 Introduction HI (Height of Instrument) Measurement T ape The HI measurement tape, Figure 1.7, is used to measure height of the GPS antenna over the survey point. The end of the tape hooks on to the antenna. The tape is extended unti l the spike on the tape case is on the point.
6 Promark2 User’ s Guide Office Receiver Bracket with Download Cable The of fice receiver bracket with integrated download cable, Figur e 1.9, is an interface device that connects the ProMark2 receiver to an of fice computer for downlo ading of stored GPS satellite data.
Introduction 7 Introduction The Ashtech Solutions post-processin g software, Figure 1.1 1, provides the to ols required to download and process the GPS satellite data from each ProMark2 receiver to produce relative positions of all point s surveyed. Ashtech Solu tio ns is provided on a CD which also contains a user ’ s guide.

14 Promark2 User ’ s Guide Surveying with Pr oMark2 The ProMark2 system is designed to perfor m GPS surveys using static, stop-and-go, and kinematic modes of GPS data collection. The three modes run independently and the GPS receiver must be turned off to run in a dif ferent mode.
Introduction 15 Introduction In the kinematic data collection mode, the GP S receiver systems simultaneously collect raw data from all available satellites while a receive r is moving. In most cases, one GPS receiver system is located on a known point serving as a base station collecting data at that location for the duration of the survey .

Getting Started 23 Getting S tarted 2 Getting S tarted Overview This chapter discusses the basic features and op eration of ProMark2. This is followed by a quick tour of the survey interf ace to show how ProMark2 can be used to collect survey data with accompanying point attribute data.
24 Promark2 User ’ s Guide T able 2.1 Control Buttons used for Survey Functions Button Description ENTER The ENTER button is used to e ither execu te the high lighted function, edit the highlighted parameter, or enter the highlighte d value. T o illustrate, refer to Figure 4.
Getting Started 25 Getting S tart ed Battery Life The ProMark2 receiver is conveniently powered by 2 standard AA batteries. Any battery type in the AA form factor can be used in the ProMark2 receiver , incl uding both disposables (alkaline, lithium) and Rayovac® IC3 rech argeables.
26 Promark2 User ’ s Guide As is evident from the graph of the alkaline batteries, temperature plays a large part in the operational life. This is true for all battery types with the exception of lithiums. The lithiu m experiences little effect on operational life due to temperature, making lithium the best choice for low-temperature operation.
Getting Started 27 Getting S tart ed The final battery alarm is the Ex treme Low Power alarm, Figure 2.4. When this alarm appears, the active survey data file is closed and the recei ver is shut down after 10 seconds. The current batteries will need to be replaced in order to continue with the survey Figur e 2.
28 Promark2 User ’ s Guide Installing Batteries T o install batt eries, remove the battery compar tment cover as shown in Figure 2.5. Remove old batteries, if any , and instal l new batteries, observ ing polarity as indi cated. Replace cover and tighten retaining screw .
Getting Started 29 Getting S tart ed 2. Delete data from r eceiver after processing. Keep the data files in the receiver until afte r you have completed the processing. If a data file were corrupted during down load, this procedure will provide you wit h the opportunity to downl oad the file once again.
30 Promark2 User ’ s Guide Downloading Collected Data to Office Computer After you have collected data in the field, you must download the data to an office computer and process the data using the Ashtech Solution s software. Use the following procedure to download the receiver data.
Surveying with ProMark2 31 Surveying with ProMark2 3 Surveying with the Pr oMark2 System This chapter presents step-by-step procedures for performing a G PS survey with the ProMark2 system. Review this chap ter thoroughly b efore attempting to perform your first survey .
32 Promark2 User ’ s Guide . If you were to perform this survey wit h a conventional total station, you w ould probably p lan on running a closed-loop traverse from the existing control point through the two new poi nts, Figure 3.2. Th e same philoso phy can be used for GPS surveys.
Surveying with ProMark2 33 Surveying with ProMark2 horizontal and 3 existing vertical control po ints. Again, if you were to perform this survey with a conventional tot al station, you w ould design a traverse plan which produced a strong looking netw ork of closed-loop traverses through t he points of the survey .
34 Promark2 User ’ s Guide Although the netw ork design in Figure 3.4 w as produced with conventional traversing in min d, this same design can also be used if performing the survey with GPS equipment.
Surveying with ProMark2 35 Surveying with ProMark2 our 3-point control survey network design, shown agai n in Figure 3.6. Assume that a 2-receiver ProMark2 system will be used to perform the survey in Figure 3.
36 Promark2 User ’ s Guide T o execute this network design, you must perfor m a direct GPS observat ion between all points directly linked. Each link can be viewed as a required GPS vector . Counting the links in this network design, you will fi nd that 19 GPS vectors are requ ired to execute this design.
Surveying with ProMark2 37 Surveying with ProMark2 The observation plan shows that it will take 10 separat e observation sessions to complete the survey based on the network design in Figure 3. 7.
