However, for BPS positioning, you will need to be in signal range of four transmitters, and even then, accuracy will be in the order of a 100-meter radius. <br><a href="https://www.tomshardware.com/service-providers/tv-signal-based-bps-tested-as-fallback-for-gps-digital-tv-infrastructure-could-come-to-the-rescue-if-satellites-are-compromised" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">tomshardware.com/service-provi</span><span class="invisible">ders/tv-signal-based-bps-tested-as-fallback-for-gps-digital-tv-infrastructure-could-come-to-the-rescue-if-satellites-are-compromised</span></a></p>
