TRACKPOINT 3 INSTALLATION INSTALLATION This section includes instructions for designing and implementing a 4610B hydrophone mounting assembly, making proper attachment of the deck cable and back panel interconnects. It also in- cludes suggested mounting arrangements for the Model 4211A (3" Hydrophone) and Model 4740A VRU/Amplifier Assembly.
TRACKPOINT 3 INSTALLATION 2.1.1 4610B SUGGESTED HYDROPHONE MOUNTING ASSEMBLY The main function of the mounting assembly is to support the hydrophone vertically in the water. Mount it at reasonable distance from the vessel's hull and below the level of the keel. The mount- ing should be rugged enough to withstand the expected forces during the planned operation, and easy to raise and lower.
Page 32
TRACKPOINT 3 INSTALLATION FIGURE 2-1 Attach the pipe to the side of the vessel so that the pipe and hydrophone assembly can be easily removed and set on board, if required, to tie the vessel up alongside other vessels or at dockside.
TRACKPOINT 3 INSTALLATION A cradle or stop should be used to ensure that the hydrophone returns to the same position each time it is deployed. 2.1.1.1 ATTACHING MOUNTING BRACKET TO PIPE The hydrophone mounting bracket typically attaches to the mounting pipe by drilling two 1/2-inch (13-mm) holes through the end of the pipe.

TRACKPOINT 3 INSTALLATION distance is a minimum of 1 meter. It is also important to keep the hydrophone below the level of the ship's keel for good 360 degree coverage. When designing the hydrophone mount/deployment system keep in mind that the shaft be keyed to allow a repeatable bearing orientation.

TRACKPOINT 3 INSTALLATION 2.2.6 SIM - SYNCHRONIZATION INTERFACE 2.2.6.1 SIM - REMOTE-IN TRIGGER The TrackPoint can be externally triggered via the rear panel SYNCHRONIZATION connector (MS- 3102A-20-29S). A mating connector (MS-3106A-20-29P) can be connected between an external key source (trigger source can range from TTL to +15V) and the TrackPoint Interface Module. See Figure 2-13.
TRACKPOINT 3 INSTALLATION 2.2.6.2 SIM - TRIGGER-OUT The TRIGGER-out is a differential TTL-compatible pulse occurring at the time of interrogation for a transponder or a responder. This TRIGGER out pulse is present simultaneously with the leading edge of each interrogation pulse. The output can be configured as either differential or positive / negative single ended when used the COMMON line.
TRACKPOINT 3 INSTALLATION 2.2.7.1 DEPTH INPUT The analog output voltage from a depth sensor (typically located on a vehicle being tracked) con- nects to the HDG/ VRU / GYRO DEPTH input connector (MS3102A-24-5P) located on the rear panel (See Figure 2-14). The TrackPoint converts this analog voltage (0 - 6 VDC maximum) to a target depth.
TRACKPOINT 3 INSTALLATION C A U T I O N Before wiring gyro confirm that the REFERENCE voltage sent from the gyro to the C/DM is within tolerance of the S/AC specified, e.g., an option 114 S/AC requires the reference voltage be less than 28.6 VAC.
TRACKPOINT 3 INSTALLATION same protocol. The RS232 Format NMEA ORE (NMEA 0183 type format string that is proprietary to ORE Offshore and includes pitch and roll data at end of string) is dif- ferent in that it outputs data in the same polarity as its incoming voltage. This allows pass-through of signals from remote VRU to integrated navigation system without modification of polarities.
Page 51
TRACKPOINT 3 INSTALLATION NOTE: Almost all vessels have a centerline weld or plank that runs down the deck that can be used for alignment purposes. If your vessel has a seamless deck, you have to measure the vessel beam and determine the true centerline. Weight a line to suspend the acoustic tracking source vertically in the water.
TRACKPOINT 3 INSTALLATION 2.3.2 HYDROPHONE X AND Y OFFSETS AND HYDROPHONE DEPTH Hydrophone Offsets are used to reference the target position to the pitch / roll center of the vessel and also to correct for the hydrophones dynamic motion. Hydrophone motion is due to the pitching and rolling of the vessel when it is not on the pitch or roll center of the vessel.
Page 55
TRACKPOINT 3 INSTALLATION The hydrophone is represented in the tracking window by a small H. Note that the H shifts to the right along the X-axis when the positive X offset (7 meters) is entered. The H moves down, parallel to the Y-axis, when the negative Y offset (-10 meters) is entered. The target continues to be tracked and now displays X and Y data in relation to the pitch / roll center of the vessel.
TRACKPOINT 3 INSTALLATION 2.3.3 HYDROPHONE-VRU OFFSET The VRU offset is the difference in angle between the installed hydrophone and vertical (static off- set). (It can also represent the offset between the Remote Dynamic Motion Sensor and the Hydro- phone.) Offsets can occur either due to a mis-aligned hydrophone or from changes in trim to the vessel.

TRACKPOINT 3 OPERATION by multi-path or extraneous noise in the water, are ignored. The lowest threshold setting increases the sensitivity of detection by recognizing smaller signals. In a high-noise environment this can lead to erratic readings. In a high-multi-path environment, lower settings result in earlier detec- tion, reducing the inclusion of multi-path signals with the original signal.

"Multiple Target Tracking" consists of a maximum of any of the following combinations of target types that can be enabled at one time (each transponder or re- sponder can also include telemetry): 4 Transponders 1 Responder...
TRACKPOINT 3 OPERATION 3.4.1 TRANSPONDER MODE Acoustic Transponder Mode To establish tracking in the Transponder mode, you must have the proper interrogation trans- ducer and transponder(s) must be operational and in the water. NOTE: The interrogation transducer inside the Model 4610B hydrophone has an optimal fre- quency range of 17 to 20 kHz.
TRACKPOINT 3 OPERATION measured by the hydrophone), and therefore, this speed of sound generally differs from that com- puted by the operator from a reading of the hydrophone temperature. (The hydrophone tempera- ture is used only to determine the target depression angle correction.) Target Depth The target depth parameter can either be manually entered, telemetered or input via analog-in Depth BNC.
TRACKPOINT 3 OPERATION The TRIG-OUT pulse NOT ISOLATED and it occurs on both the transponder (transmit) and re- sponder trigger cycles. The responder itself must be operational and in the water. Refer to the instruction manual for the particular responder in use. Follow the steps outlined in the TRANSPONDER section, 3.3.2, to choose a target, set the frequency, turn tracking on for that target and enter depth.
TRACKPOINT 3 OPERATION 3.4.4 CONSECUTIVE VS SIMULTANEOUS Consecutive Tracking VS Simultaneous Tracking: The Model 4450A (aka TP3) contains only one Target Acquisition Module (TAM) and tracks up to four Beacon in sequence (“consecutively”) while the Model 4450A-S (aka TP3-S) has four Target Acquisition Modules and tracks up to four Beacons simultaneously or consecutively or a combina- tion of simultaneously/consecutive targets.

TRACKPOINT 3 ERROR AND WARNING CODES A number of situations can occur which either prevent calculation of the position or can lead to misrepresentation of the data. If calculations cannot be performed on the data received, a message is displayed in the Status Block and an ERROR CODE is sent out on the RS-232.
Page 134
TRACKPOINT 3 BRIEF ERROR CODE LISTING CODE TARGET ERROR DESCRIPTION depth to calculate horizontal range. Horizontal range calculated to be greater than slant range. Low Quality Factor NOTE: Error codes less than 20 result in no new position updates, while error codes of 21 or greater are warnings.
Page 135
TRACKPOINT 3 EXPLANATION OF ERROR CODES CODE DESCRIPTION # TOD HDG BRG S.R. TEL ERR 1 02:12:04 1 02:12:06 When an Error Code 6 occurs, -.- lines are sent out the RS-232 as shown above to indicate invalid data within those data fields. Minimum range error.
Page 136
TRACKPOINT 3 EXPLANATION OF ERROR CODES CODE DESCRIPTION Pinger Only: This warning applies only when hydrophone offsets are entered and when track- ing a pinger where its depression angle is < 20° from the horizontal. Its purpose is to notify the on-line computer system, via the RS-232, that all ranges and x or y coordinates to that target are minimum values and generally do not indicate actual ranges.
Page 137
TRACKPOINT 3 EXPLANATION OF ERROR CODES CODE DESCRIPTION When tracking a transponder or responder in calculated depth mode and the target's depres- sion angle is < 45° from the horizontal, this error code warns that the system is no longer calculating depth in determining target position.
TRACKPOINT 3 OPERATION TROUBLESHOOTING ACOUSTIC PROBLEMS 3.6.1 TRANSPONDER MODE A transponder emits an acoustic signal of a known frequency in response to an acoustic interroga- tion pulse sent from the TrackPoint II transmitter. The primary advantage of using a transponder is that the target range can be measured directly from the round-trip travel time of the acoustic signals.
Page 139
TRACKPOINT 3 OPERATION when the transmitter is turned back on, still with erratic ranges. If this is occurring, the operator should lower the output power of the TrackPoint transmitter by changing the output jumper on the transmitter board, or increase the transponder's lock-out time and use a longer interrogate inter- val.
TRACKPOINT 3 OPERATION If a slower repetition rate does not solve the problem (or if the repetition rate is already slower than two or three seconds), the operator should try to isolate the sources of multi-path and resolve the independent factors using the above guidelines. Transponder responds correctly and hydrophone receives correctly giving accurate slant ranges but erratic bearings.
TRACKPOINT 3 OPERATION RS-232C INTERFACE “TrackPoint Signal Interface Module” 3.7.1 GENERAL COM#1 “USBL to PC” The TrackPoint 3 Console uses the standard EIA RS-232C serial communications interface to com- municate with the PC. This can be configured from the DEVICE LIST “TrackPoint 3” dialog box by setting the BAUD RATE, the number of DATA BITS required and the number of STOP BITS.
TRACKPOINT 3 OPERATION 3.7.2 HARDWARE COM#1 “USBL Deck Unit” The TrackPoint COM#1 interface is designed to act as a “DCE” (Data Communication Equipment) device. This means that it will interface directly to “DTE” (Data Terminal Equipment) device (E.g. Processor Module or PC), with the TrackPoint acting as if it were a modem. That is to say, a Null modem is NOT required between the Processor (PC) and the TrackPoint 3 Console.
