Introduction

What is the ProMark2 Survey System?

ProMark2 is a complete GPS system providing both navigation and precision surveying. The ProMark2 system, Figure 1.1, includes two or more ProMark2 GPS receivers, GPS antennas, and all ancillary components required to get you up and running and producing quality survey data in a minimum amount of time. Please note that the kinematic initialization bar (Figure

3.27), which is currently included in systems containing two or three receivers, is not included in Figure 1.1.

Introduction

Figure 1.1: ProMark2 Two-Receiver System

The ProMark2 system utilizes standard tripods or fixed-height GPS tripods to position system components above a given survey point. The ProMark2 receiver collects signals broadcast from GPS satellites, and stores this information in its internal solid-state memory. The collected data is extracted from the ProMark2 receiver via a serial data cable to an office computer for post-processing.

Introduction 1

The ProMark2 System operates in conjunction with Ashtech Solutions, Thales Navigation’s highly-automated GPS post-processing engine. Ashtech Solutions is a complete, easy-to-use software package which manages and processes raw GPS data, deriving precise positioning data and presenting the results in easily understood report formats.

Items Supplied with ProMark2

The items supplied with ProMark2 are described in the following paragraphs.

ProMark2 GPS Receiver

The ProMark2 GPS receiver, Figure 1.2, acquires and stores raw GPS satellite data at each survey point. The data from each ProMark2 is later post-processed to determine the relative position of the points surveyed.

Figure 1.2 ProMark2 GPS Receiver

2 Promark2 User’s Guide

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 external antenna is required to obtain quality data for precision surveying. The external GPS antenna is the physical data collection point for the raw GPS satellite data. For this reason, it must be accurately positioned over the point to be surveyed, using a standard tripod or fixed-height GPS tripod.

Figure 1.3 External GPS Antenna

External Antenna Cable

The external antenna cable, Figure 1.4, connects the ProMark2 receiver to the external antenna. The small end of the cable connects to the ProMark2 through the back of the field receiver bracket. The large end of the cable screws onto the external antenna.

Introduction

Figure 1.4 External Antenna Cable

Introduction 3

Vertical 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).

MapSend Streets CD

The optional MapSend Streets CD, Figure 1.10, contains detailed street-level maps that can be loaded into the internal memory of the ProMark2 receiver. These detailed maps can then be used with the navigation functions of the receiver to assist in navigating to the job site. Be aware that the maps and the raw GPS satellite data occupy the same internal 8 megabytes of memory, thus the larger map you load, the less survey data you can store.

Fixed-Height GPS Tripod

An option to the tripod, tribrach, and tribrach adapter combination is the fixed-height GPS tripod, Figure 1.15. The fixed-height GPS tripod has the advantage of eliminating the possibility of measuring and/or recording an incorrect HI, since the height is fixed. HI blunders are one of the most common mistakes during data collection.

Introduction 13

Surveying with ProMark2

The ProMark2 system is designed to perform 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 different mode.

In the static data collection mode, the GPS receiver systems simultaneously collect raw data from all available satellites while remaining stationary on their respective points. Data collection continues at these locations for a duration dependent upon the distance between the receivers, the satellite geometry, and the obstruction conditions at the data collection locations (i.e., trees or buildings blocking some of the sky). When data collection is complete at these specific points, you move the GPS receiver systems to a new set of points to begin another data collection session. In most cases, one GPS receiver system will remain on its current point (pivot point) in order to link the previous set of points to the new set of points, in leap-frog fashion. After data collection is complete, data is downloaded form the GPS receivers to an office computer for post-processing using the Ashtech Solutions software. The postprocessing activity computes vectors (position differences) to determine the position of all observed points relative to one or more fixed point positions. The static data collection method produces the most accurate and reliable results of any mode of GPS data collection. This is due primarily to the extended observation periods required for static data collection.

In the stop-and-go data collection mode, the GPS receiver systems simultaneously collect raw data from all available satellites while stationary on their respective points and while moving between points. 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. Additional GPS receiver systems are used to locate objects and move between points. The occupation period for the stop-and-go method is much shorter than the static method. After data collection is complete, data is downloaded form the GPS receivers to an office computer for postprocessing using the Ashtech Solutions software. The post-processing activity computes vectors (position differences) to determine the position of all observed points relative to one or more fixed point positions. The stop-and-go data collection method is faster than the static method, but not as accurate since the occupation period is much shorter.

14 Promark2 User’s Guide

In the kinematic data collection mode, the GPS receiver systems simultaneously collect raw data from all available satellites while a receiver 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. Additional GPS receiver systems are used to locate linear objects such as roads or collect data in a linear fashion for developing topographic elevation data. The recording interval should be set to collect the amount of data needed relative to the speed of travel. A recording interval too long will result in insufficient data. A recording interval too short will result in too much data. After data collection is complete, data is downloaded form the GPS receivers to an office computer for post-processing using the Ashtech Solutions software. The post-processing activity computes positions of all observed points relative to one or more fixed point positions. The kinematic data collection method is best used for delineating linear type features such as roads, fences, lakes, etc.

Navigating with ProMark2

The ProMark2 includes a wide range of navigational capabilities that you will find useful in your day-to-day surveying operations. Two useful navigation features are:

• The street database and map screen can be utilized to help you find a project site.

• The ProMark2 serves as an excellent reconnaissance tool. You can enter the known coordinates of the feature you wish to recon as a waypoint, and use ProMark2 to navigate to within 3 meters (10 feet) of the feature in the field. Be sure to select the correct map datum and coordinate system (use the user-defined feature to define State Plane grid zones).

ProMark2 includes the capability to utilize the Wide Area Augmentation System (WAAS) and the European Geostationary Navigation Overlay System (EGNOS) to provide improved positioning accuracy. These systems calculate errors in the GPS signal, then transmit correction messages to capable GPS receivers. Typical accuracy with WAAS augmentation is three meters, although this accuracy can be degraded by multipath reflections and poor satellite geometry. More information on WAAS is available at the FAA web site http://gps.faa.gov/ Programs/WAAS/waas.htm. More information on EGNOS is available at http://www.esa.int/ EGNOS/.

For details on how to utilize your ProMark2 receiver for navigation, refer to the MAP330 User Manual.
