Introduction The CAT PRO is a dual antenna solution, providing an RTK position and heading independent from the ship’s instrumentation. The built-in rate gyro offers precise and independent Rate of Turn, providing a reliable inertial platform needed for crucial positioning predictions; this being especially important in critical turns.
What’s in the box The box is water and shock proof 2 x CAT PRO - fully interchangeable HDG / POS receivers 1 x CAT EXTENDER – AIS forwarder and network extender 2 x Mounting bracket 1 x Y-cable – Charging and Pilot Plug 2 x Charging cable 1 x USB Multicharger 1 set of world adapters...
Operational modes As mentioned in the introduction the CAT PRO can be utilized in four different operational modes. This ensures maximum flexibility that will suit all types of vessel maneuvers. In the following the modes and the setup are described. 1.
6. Connect an iPad to the network “CAT PRO (xxxxxxxx)” with password “86912255” and open up SafePilot. 3. CAT PRO as stand-alone system In Mode 3 the CAT PRO acts as a complete independent system, not relying on any of the ship’s instrumentation.
4. CAT PRO as stand-alone system with AIS and extended Wi-Fi Range In Mode 4 three units are used, the CAT EXTENDER and both CAT PRO’s. The CAT EXTENDER will act as the Wi-Fi access point and will forward AIS information from the ship. Having the CAT EXTENDER in the center of the ship, will give a strong and reliable Wi-Fi coverage throughout the entire bridgewing, even on the largest ships such as ULCVs.
Wi-Fi – optimal usage The Wi-Fi strength is slightly directional in the CAT PRO, and to obtain the best performance it is important to place the units according to the instructions below. The strength is highest in the directions of the arrow. 1.
3. CAT PRO as stand-alone system The CAT PRO’s are placed with the arrow pointing towards the wheel house and on the bridgewing where the pilot is located during docking. 4. CAT PRO with Extender and the units on same bridgewing The Extender is placed with a clear view towards the bridgewing where the two CAT PRO’s are located and the CAT PRO’s are placed with the arrow pointing towards the wheel house and on the opposite bridgewing where the pilot is located during docking.
5. CAT PRO with Extender and a unit on each bridgewing The Extender is placed with a clear view towards both bridgewings where the two CAT PRO’s are located and the CAT PRO’s are placed with the arrow pointing towards the wheel house. Wi-Fi strength is equally strong on each bridgewing.
Position and Heading The CAT PRO position unit provides position, speed, and course. It communicates GNSS corrections to the CAT PRO heading unit for it to compute a heading. The accuracy of the heading depends on the distance between the CAT PRO position and CAT PRO heading. At 4m baseline the accuracy is 0.05°, by extending the baseline further the accuracy will become better.

Figure 1 Optimal location - no obstructions nearby Figure 2 Bad because of the vertical wall next to the unit. A very large part of the sky is blocked and the wall close by will cause multipath...

Figure 3 Bad because the wheelhouse is too close and blocking 40% of the sky Figure 4 Compromise because antennas block large part of the sky and they might transmit high power Figure 5 Compromise because pipes are next to and above the CAT PRO...
Position Quality In the sensor view in SafePilot information about the quality of the position, speed and heading is shown. If the quality indications described below is not satisfied, the location of the unit should be revised. Guideline for a good position: •...

In “Floating Ambiguities” it will compute a heading, but the quality is not good enough (above 0.5 degree). In “Fixed Ambiguities” the quality of the heading is good and is shown. • The HDG standard deviation is the minimum accuracy of the heading. This must be lower than 0.5 for a heading to be showed.
Pilot Plug Mode The CAT PRO or the CAT EXTENDER can be fitted in the Pilot Plug of the ship to receive AIS targets from the ship’s AIS. Using the CAT EXTENDER in Pilot Plug If using the CAT EXTENDER, connect this to the pilot plug to receive AIS targets. Adding to this it has the advantage that, the CAT EXTENDER will be in the center of the bridge, ensuring a good Wi-Fi coverage over the entire bridge.
Charging interface The CAT PRO features two charging options, either by cable or via a wireless charge pad. The CAT EXTENDER can only be charged through a cable. Cable Charging When connecting the cable charger cable, the CAT PRO will start to flash red, to indicate it is charging. When fully charged it will flash a solid red.

Common Errors and Troubleshooting No Wi-Fi connection to iPad: • Do not lay the iPad on a metal surface, it will decrease the Wi-Fi connectivity. • If using the CAT EXTENDER, make sure it is placed in a central place on the bridge. Make sure no obstacles is in the very near proximity of the antenna.
Firmware Update If a newer firmware is available, it is recommended to upgrade to the latest version. To update the units, it is done Over the Air (OTA) via SafePilot. Feature not implemented yet.
