From: Understanding and geo-referencing animal contacts: proximity sensor networks integrated with GPS-based telemetry

Minute Action Expected event Reason for expectation
1 Stop No contact Distance M1–L1 and M1–L2 > 2.38 m
2 Stop No contact Distance M1–L1 and M1–L2 > 2.38 m
3 Stop No contact Distance M1–L1 and M1–L2 > 2.38 m
4 Stop No contact Distance M1–L1 and M1–L2 > 2.38 m
5 Movement Start contact with L1 Distance M1–L1 < 2.38 m
GPS triggered Detection of a contact
6 Movement In contact with L1 Distance M1–L1 < 2.38 m
7 Movement In contact with L1 Distance M1–L1 < 2.38 m
8 Stop End of contact with L1 Distance M1–L1 > 2.38 m
9 Movement Start contact with L1 Distance M1–L1 < 2.38 m
GPS triggered Detection of a contact
10 Movement End of contact with L1 Distance M1–L1 > 2.38 m
11 Movement Start contact with L2 Distance M1–L2 < 2.38 m
GPS triggered Detection of a contact
12 Movement End of contact with L2 Distance M1–L2 > 2.38 m
13 Movement No contact Distance M1–L2 > 2.38 m
14 Movement Start contact with L2 Distance M1–L2 < 2.38 m
GPS triggered Detection of a contact
15 Stop In contact with L2 Distance M1–L2 < 2.38 m
16 Stop In contact with L2 Distance M1–L2 < 2.38 m
  1. Example of a 17-min trial ‘script’ for testing contact detection and contact-triggered GPS location acquisition with WildScope loggers, deployed in a mixed network (mobile and fixed loggers). The script refers to the first scenario (Fig. 2, one mobile logger M1 and two fixed ones, L1 and L2), with loggers set at power 3 where the expected contact detection threshold is 2.38 m [19]. The table refers only to the actions taken by the mobile logger. Both expected contact detection and contact-triggered GPS location expected events are reported, with the associated reason for expectation
