  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
