1. RTK Mode - Static Testing Objective: Evaluate whether the positioning accuracy of the EX-1 in a stationary position meets the nominal value. Duration: 1 hour | Update Rate: 1 Hz | Date: UTC 2024-07-24 15:37:16 ~ 16:37:15 Method: The receiving antenna was completely stationary, collecting 3,600 continuous track points to calculate the CEP value based on the average position. Conditions: Conducted on a rooftop with open sky, approximately 100 meters RTK baseline distance. Click to download the original data recorded by the EX-1> Conclusion: The CEP (50%) accuracy was 0.002633m, exceeding the nominal value of 0.01m. This means that half of the positioning points fell within a circle centered on the average position, with a radius of 0.002633m. The CEP (100%) accuracy also achieved an excellent 0.010303m.

2. RTK Mode - Dynamic Testing Objective: Evaluate the positioning accuracy of the EX-1 during movement. Duration: 96 seconds | Update Rate: 1 Hz | Date: UTC 2024-07-24 20:55:09 ~ 20:56:44 | Laps: 1 lap Method: The phase center of the antenna was placed at the edge of a disk with a diameter of only 40 cm, rotating at a speed of approximately 90 seconds per lap (linear speed of about 1.4 cm/second). Conditions: Conducted on a rooftop with open sky, approximately 100 meters RTK baseline distance. Click to download the original data recorded by the EX-1>

The left and right images were recorded synchronously during the test.

Conclusion: Recording ultra-low-speed motion tracks presents significant challenges for RTK devices. In this test, the EX-1's motion track coincided with a circle of 20 cm radius in the target diagram, confirming the disk's radius as 20 cm.

3. RTK Mode - Dynamic Stability Testing Objective: Evaluate the tracking accuracy of the EX-1 during movement. Duration: 927 seconds | Update Rate: 1 Hz | Test Time: UTC 2024-07-22 16:36:09 ~ 16:51:35 | Laps: 10 laps Method: Same as the "Dynamic Testing," recording the track over ten continuous laps. Conditions: Same as the "Dynamic Testing." Click to download the original data recorded by the EX-1>

	The above image shows a close-up of the track (1 cm/div).

Conclusion: The consistency of the track during continuous laps was excellent, with a width maintained at around 1 cm throughout.

4. SBAS Mode - Stand-alone Static Testing Objective: Evaluate whether the positioning accuracy of the EX-1 in a stationary position meets the nominal value. Duration: 1 hour | Update Rate: 1 Hz | Date: UTC 2024-08-22 23:16:06 ~ 2024-08-23 00:16:05 Method: The receiving antenna was completely stationary, collecting 3,600 continuous track points to calculate the CEP value based on the average position. Conditions: Conducted on a rooftop with open sky, achieve differential satellite positioning throughout. Click to download the original data recorded by the EX-1>

Conclusion: The CEP (50%) accuracy was 0.240130m, exceeding the nominal value of 0.3m.
