Pilot Watcher is a software-based product that runs on an Android tablet and connects to DingLi's remote measurement probes e.g. Pilot RCU, Pilot RCU Light, and Pilot Scout through WiFi for real-time service test monitoring. It specifically displays the performance and measurements captured from test modules used by the remote probes. This may include 2G, 3G, 4G, 4G 3CC, and LTE-IoT multi-technology measurement.

Some of the information includes the test modules'parameters, events, MOS score, alarms, GPS-based test routes, test plans, device status, etc. Pilot Watcher is designed for onsite drive test technician or engineer to directly monitor the test modules and network status, display messages details in real time, replay logfiles, and generate statistics reports during the service test. In addition, users may set various forcing functions in Pilot Watcher for the test modules, such as network, band, channel number and cell lock, etc. It can also send commands to power on/off or reboot the remote probes. Pilot Watcher can monitor the remote probe test measurements, both when it is connected to or disconnected from Pilot Fleet Unify. The options will help to improve the operational efficiency by ensuring the test process continuity in case of unavoidable remote network interruption.

Pilot Watcher can now connect to a mini high-accuracy pinpointing device (integrated with a gyroscope) called "WALK", through the Android tablet's Bluetooth connection, where the tester's indoor navigation (e.g. pinpointed indoor location) is automatically and accurately positioned. This means automated navigation for indoor multi-network test can be executed. The "WALK" device can sense the tester's walking direction and speed, and accurately (positional accuracy deviation less than 0.1%.) position it on the indoor map. This makes Pilot Watcher an ideal solution for indoor network test and measurement.

Indoor Test---Features & Functions

• Multiple indoor test scenarios
Indoor test scenarios: building floor, stairs, escalator, and elevator
• Fully-automatic & accurate positioning for long distance
"WALK" can sense the tester's walking direction and speed accurately, and the positioning frequency will be automatically adjusted according the tester's walking speed. In addition, test route with any directional shape (e.g. ring-shaped or 8-shaped route) is supported.
Automatic indoor positioning may be conducted continuously for long distance test, which is applicable in big buildings scenario.
• Map-based positioning & no map-based positioning
Users may import *.JPG/*.BMP map file (e.g. fire services plan or floor plan taken by Android tablet), on which users may conduct positioning test.
Users may also directly conduct positioning test on Pilot Watcher's default interface without importing a map.
• Zoom in/out the map/interface during positioning test
Users may zoom in/out the map or Pilot Watcher's default interface in real time during the test to view the test route more conveniently and clearly.
• Switch test scenarios during positioning test
Users may switch test scenarios as required without ending the test. Users may also select whether to switch the log when switching the test scenario.
• Calibrate the gyroscope within "WALK"
Users may calibrate the gyroscope within "WALK" during the test.
• Quick connection with "WALK"
"WALK" device (integrated with a gyroscope) can be automatically connected/reconnected to Pilot Watcher.
• Component with low power consumption
Fully-charged "WALK" can be used over a long duration, and therefore users need not charge the "WALK" device as frequent.
• Automatic sensing during elevator test
"WALK" (integrated with a gyroscope) can automatically sense the current floor when the elevator moves up/down during the test.
• Stairs test
"WALK" can sense the tester's walking direction (e.g. turning left or right), and therefore WALK device supports test route with any directional shape (e.g. ring-shaped or 8-shaped route).

Gyroscope and GPS integration for real time positioning with Pilot Watcher can successfully compensate GPS trajectory error in case of insufficient visible GPS satellites for determining a train position. Before the test, users need to connect the gyroscope and GPS antenna to Pilot Scout/Pilot RCU to a USB interface.

Users need to place the gyroscope horizontally in a position where the arrow head is pointing to the train's forward direction. Select the rail line, rail number, current station and end station, and send those information through Pilot Watcher to the remote probe before executing the test. The remote probe positioning will start automatically once the high-speed rail starts to move. Throughout the positioning process, the remote probe with gyroscope and GPS antenna will automatically sense the start or stop stations.

High-speed Rail Test ---Features & Functions

• Test solution with gyroscope and high-accuracy GPS antenna
Pilot Watcher can accurately sense the current train location, and users can switch between GPS based positioning or gyroscope positioning as required, where scientific algorithm is applied to calculate the train location, which is mostly in closest proximity to the actual train location. This makes Pilot Watcher an ideal solution for high-speed rail test.
• Test solution with gyroscope
In the situation where there is no GPS signal, users can also connect the gyroscope to the remote probe to pinpoint a test route positions based on the train heading direction.
• Automatically calculate whether the train arrives at/starts from the station
The gyroscope can automatically calculate whether the train arrives at or starts from the station during the whole test process.
• High-speed rail line and number update
Users may update high-speed rail line and number information online in Pilot Watcher, and do not need to copy the file manually.
• Proceed with positioning even if the test is interrupted with exceptions
The positioning will continue from the last used position of the previous test, if the remote probe is rebooted. Therefore, the test route positioning will be presented as comprehensive as possible. This eliminates the need to re-do the test which can be cost inefficient.
• Real-time Monitoring
Users may monitor radio parameters, messages, events and device status in Pilot Watcher or Pilot Fleet Unify in real time.
• Manual operation to start/proceed with pinpointing
If Pilot Watcher fails to automatically calculate when the train arrives at or starts from the station accurately because of unknown factors, the test technician or engineer may proceed to manually pinpoint the position by tapping relevant icons in Pilot Watcher. For example, tap a certain button which means "start pinpointing" to start pinpointing, if Pilot Watcher fails to calculate when the train starts from the station accurately and hasn't started pinpoint the position automatically. Another example:tap another certain button which means "pinpointing continued" to proceed with the pinpointing, if Pilot Watcher fails to calculate when the train arrives at the station accurately and has stopped pinpoint the position automatically.
