An In‑Depth Review 1. Introduction The November 2009 issue of SubRang Digest arrives at a pivotal moment for the niche community it serves—advanced hobbyist and professional users of sub‑range (sub‑micron) positioning and sensing technologies. The publication, now in its fifth year, has steadily evolved from a modest newsletter into a full‑blown technical magazine, and the November issue is arguably one of its most ambitious to date. It packs twelve feature articles, three regular columns, a “Tools & Kits” spotlight, a “Community Corner,” and a dense “Research Highlights” section that together run over 120 printed pages. subrang digest november 2009
