Iridium GO! and data transfer : the disappointment

My previous post entitled Iridium GO! keeps its promises, functionally no doubt. But I also wrote :

[...] baud rates identified during my tests, with systematic passage of satellite over my position, were disappointing : from 39 up to 52 seconds to connect to the server, download speeds 1119 up to 1616 bps at best. To compare, with Iridium 9575 and external fixed antenna, I got the connection time of 14-15 sec. and download rates that have often largely exceeded the 2400 bps up to sometimes more than 3000 bps (³). Only flip-up antenna of GO! seems inadequate, the slow rate of transfers increasing the connection time and the final invoice.

I have therefore undertaken, Thanks to my partner E SAT which let me use this device with adding the antenna connector, test by connecting Iridium GO! an external Sailor antenna, already used two years ago for a comparison between Iridium and IsatPhone (¹).

Iridium GO! keeps its promises [Update]

Since its announcement last February, the GO! is expected to come from dealers at the beginning of this month. Company E SAT gave me one to conduct some tests. Although too late to perform these tests at sea, the Quai des Antilles on the island of Nantes offers a wide clearance also than the deck of a boat, enough to capture satellites of all-round. Two types of test were conducted : requests and receipts of GRIB weather files from an iPad featured with Weather4D PRO app, functions related to the telephony from an iPhone.

Navionics charts trade policy [Update-5]

Trade policy for Navionics charts purchased on the website x - has - again - been reviewed in recent weeks, at the same time as the 'My Account' page has changed. These changes are unfortunately not all positive.

The renewal of the charts purchased was proposed for two years at a price of half of the initial purchase price, what had seemed a reasonable offer. This offer is gone for mobile media, and is maintained only for MacENC and applications for PC. This means that users who want to keep their charts updated beyond the first year must renew their chart folder at the initial purchase price. I find this totally counterproductive, as this will encourage many users of this excellent mapping not to renew their files and use them in the State for several years.
