Project update 3 of 7
Comparison Test: Rover Power Consumption
by Sharon WangWe are thrilled to share our second update!
This week we conducted a power test to evaluate the performance of three different devices: the Hyfix Rover, Ublox F9, and Septentrio Mosaic GO. We utilized a common antenna setup and the powerful "STRSVR" utility from RTKlib for data logging.
Power Test Setup
We connected the three receivers to a single GPS splitter connected to a common antenna. This allowed us to simultaneously test and record data for all the devices while keeping the test environment consistent.
Introducing Power Measurement
We used a USB power receiver to record the power consumption of each device. This receiver enabled us to monitor the power consumption of each rover when plugged in. At the end of the test that was conducted in the first update post, the USB tool was inserted into each device yielding the following results:
| Device | Voltage | Current | Power |
|---|---|---|---|
| Hyfix RTK Rover | 05.111 V | 0.0710 A | 0.35 W |
| Septentrio Mosaic GO | 05.081 V | 0.2273 A | 1.10 W |
| Ublox F9 | 05.093 V | 0.1799 A | 0.91 W |
Analysis
- Voltage: The voltage readings for all three devices were close, with the Hyfix Rover having the highest voltage at 5.111 V and the Septentrio Mosaic GO with the lowest at 5.081 V. The voltage difference among the devices is minimal, suggesting they are all operating within a similar voltage range.
- Current: The current readings show more significant differences among the devices. The Septentrio Mosaic GO draws the highest current at 0.2273 A, followed by the Ublox F9 at 0.1799A, while the Hyfix Rover at 0.0710A draws the lowest current of the three.
- Power: The Hyfix Rover has approximately 0.35 W of power consumption, followed by the Ublox F with approximately 0.91 W, and finally the Septentrio Mosaic GO with about 1.10 W.
The power consumption results highlight that the Hyfix Rover is optimized for power efficiency. This makes it a suitable choice for applications where conserving power is crucial. The power efficiency of the devices plays a critical role in determining their overall performance and battery life. The Hyfix Rover proves to be the most power-efficient device among the three devices. Way to go! Next Update: In our next post, we will be sharing the results of a different test that will be conducted. Stay tuned for more updates.
