Navman Announces Highly Sensitive Jupiter 30 GPS Chip
There’s a new GPS chip in town, and the Jupiter 30 ready to take on the highly sensitive chips that have been recently introduced into the marketplace. Navman is claiming that their new Jupiter 30 GPS module is sensitive enough to pick up signals in natural canyons, urban canyons and even indoors. The module can either be a standalone device or embedded into third party GPS navigation systems. Capable of detecting signals as weak as -160 dBM, the Jupiter 30 brings GPS tracking to previously "impossible locations," Navman said.
The Jupiter 30 is small, about the size of a Compact Flash memory card, and weighs four grams. It can track up to 20 GPS satellites simultaneously (out of a 24 total, which is similar to the SiRF executions) and Navman says that horizontal positioning is within 9.5 feet. It also has a pretty good time to first fix capability: less than a second for a hot start (it’s in the same location as when it was recently turned off) and about a half a minute for a cold start (needs to determine where it is from scratch).
We’ve seen the SiRF star III chip pick up signals indoors on a Forerunner 205 standing on the second floor of our two story house, so it will be interesting to see if Navman is talking about similar capability or if they are talking about a big leap forward. Either way, the GPS chip capabilities continue to make big advances in quality and cost. This is great news for users.
Navman said it will be starting full-scale production of the module this month.
