Fig. 4
Comparison of one night’s movement for an individual badger according to GPS data (orange) and GPS-enhanced dead-reckoned data (blue). The left-hand panel shows a full night’s data over a period of 6 h, 52 min, 52 s. The GPS-only track, based on 67 locational fixes (a fix success rate of 81.7%) measured 3.97 km, whilst the GPS-enhanced dead-reckoned track measured 10.93 km for the same period. A woodland area around the badger’s sett is highlighted by a white rectangle, with the right-hand panel showing an expanded version of this area, highlighting the comparison of GPS-only and GPS-enhanced dead-reckoned derived movement
