I have multi-annual radio-collar location data for 28 marten and I want to calculate their multi-annual home range. I'm picking up an old project that was never completed and I am re-running the analyses. The radio collar data are from old VHF collars and the relocation interval varied between several days to weeks among individuals.

Previously, these data were analysed using KDE (fixed smoothing, LSCV, volume contouring, 800 grid size). KDE asymptote analysis on individual animals was performed, by randomly adding locations because sampling was not conducted at even time intervals. 10 iterations were performed using program ABODE.

My problem now is that the programs and extensions used in the previous analyses are now non-functional, and I can't re-run the analyses. I have noticed that some newer programs, such as OpenJUMP HoRAE can be used for asymptote analysis, but the option to draw locations at random is not an option for KDE methods. This makes sense, as most radio collar data these days are GPS/track data.

Any ideas what program to use to run my analyses?

Or alternative methods for ensuring that my location data for each animal reveals the full extent of the home range?
