Comparison between the proposed method and the relevant work_
| 2019 (Zhu et al., 2019) | 2016 (Werries and Dolan, 2016) | 2017 (Li et al., 2017) | Proposed Method | |
|---|---|---|---|---|
| GPS with IMU | Yes | Yes | Yes | yes |
| KF of modified KF | Yes | Yes | Yes | yes |
| Hardware implementation | No | No | No | yes |
| Update rate | Not mentioned | 250 m sec | Not mentioned | 10 m sec |
| Update location if GPS signal lost | No | No | No | yes |
| Integrate with IoT device | No | No | No | yes |
| Used Components | GPS + 3IMU | GPS | GPS + IMU + UWB | GPS + IMU |
| Power consumption (without microcontroller) | 79.2 + 3*10.56 = 110.88 mW | 79.2 mW | 79.2 + 10.56 + 5.3 = 95 mW | 79.2 + 10.56 = 89.76 mW |
