Pulsar Free GRIB Files

GRIB Files, Marine Weather, and Satellite Communications

Welcome to the Pulsar free GRIB file service. 

Pulsar was one of the first companies to provide free downloadable GRIB weather files in the early '00s, then under the name Global Marine Networks. We remain committed to providing marine weather information and the products and services you need to access it.

To download a GRIB file over satellite via email, the best way is with a satellite email program like XGate, connected to a satellite phone with a satellite Wi-Fi router like the RedPort Optimizer. XGate compresses data and improves email speeds to help you get the information you need over satellite - affordably and quickly. 

Need satellite service? Pulsar gives you a truly local number just like your cell phone, monthly plans, and free incoming calls on most plans.
