El Garmin inReach Mini 3 Plus (348 € HT) és l’estàndard per a navegació en solitari a França: SOS Iridium 24/7, SMS bidireccional per a fil de vida família + equip de ruting, 100 g a la butxaca de la jaqueta impermeable. Sense veu — és assumit, no es compra un telèfon, es compra una assegurança de vida que pesa 100 g.
Total cost (terminal + 1-year Garmin Standard subscription): ~ $530 USD ex-tax

El Garmin inReach Messenger Plus (279 € HT) afegeix notes de veu curtes respecte al Mini 3. No és una veritable veu per satèl·lit, però n'hi ha prou per dir 'hem arribat bé a Cala Galera, mar plana'. 28 dies d'autonomia en seguiment sense recàrrega — útil en vaixells de 30 peus sense gran capacitat de bateria.
Total annual budget (terminal + subscription): ~ 460 € HT

L'Iridium 9575 Extreme (1 573 € HT) segueix sent el nostre estàndard de taller d'alta mar durant els darrers 15 anys. Veu nativa sense dependència de telèfon intel·ligent (per tant, fiable en cas de fallada de l'electrònica de bord), antena integrada desplegable (sense instal·lació a foradar), IP65 + MIL-STD-810F (resisteix cops de mar i caigudes). Com a complement, afegir un Iridium GO per a correus electrònics i la meteorologia comprimida si la tripulació utilitza telèfons intel·ligents.
Combined budget 9575 + GO + 1-year subscriptions: ~ 3 800 € HT

L'Iridium GO Exec (2 106 € HT) sobre Certus 100 és el nostre límit satèl·lit "raonable": 88 kbps de descàrrega permeten enviar correus electrònics amb fitxers adjunts, descarregar GRIB d'alta resolució i realitzar trucades HD mitjançant l'aplicació. Més enllà — streaming de vídeo, videoconferències — cal passar a Starlink Mini Marine (~ 650 € HT terminal + 50-80 €/mes Roam Global). Skysat no comercialitza directament el terminal Starlink, però proporcionem el kit d'instal·lació (passarel·la estanca Scanstrut, cables de qualitat premium).
Total budget GO Exec + Certus 1-year subscription: ~ 4 000 € excl. VAT — or Starlink Mini ~ 1 500 € excl. VAT terminal + 1-year Roam
View GO ExecThe 3 mistakes that keep coming up when a customer chooses their satcom gear without consulting us.
The standard GO tops out at 2.4 kbps. That’s 1980. You can send a 200-word text email in 2 minutes. You cannot load a web page, make a WhatsApp video call, or download an uncompressed weather map. For real data: GO Exec (Certus 100) or Starlink Mini.
The Garmin inReach Mini 3 Plus and Messenger Plus are SMS communicators, not phones. You can send text messages (160 characters). The Messenger Plus allows recording short voice notes — not a live call. To hear a loved one’s voice from offshore, you need an Iridium 9575 or GO.
The Starlink antenna is easy to install — but the PoE cable running from the deck requires a properly sized watertight deck gland (Ø30 mm = Scanstrut DS30-SL-BLK). Without it, expect leaks at the first slamming wave. And powering the 12 V supply without an isolated converter will fry the power rectifier within 6 months of saltwater sailing.
4 questions to identify the satellite terminal suited to your program and annual budget (terminal + subscription).
Skysat no longer distributes the 9555 (obsolete model replaced by the 9575 Extreme — improved IP65 rating + MIL-STD-810F + integrated GPS). The Inmarsat IsatPhone 2 is not sold by Skysat — its geostationary satellite coverage depends on a clear horizon (problematic at high latitudes and near land). The Iridium LEO constellation provides 100% global coverage without restrictions. For our offshore sailing clientele, this is more relevant.
Yes, provided you have a Roam Global subscription (€50 or €80/month; verify the exact coverage area before departure — central Pacific remains partial in 2026). In the Mediterranean and North Atlantic, continuous sea coverage is available. Since the Starlink constellation operates in LEO (~550 km), throughput remains equivalent to terrestrial use. Real limitation: 12 V power draw (25–50 W), so proper wiring and surge protection are mandatory.
The Mini 3 Plus (348 € HT) is more compact (100 g vs 113 g), more physically durable, and has a color screen readable in full sunlight. The Messenger Plus (279 € HT) is cheaper, adds short voice notes (2025 new feature), and lasts 28 days in 10-minute tracking vs 14 days for the Mini 3. For solo racing / grab bag: Mini 3. For crewed cruising with family voice notes: Messenger Plus.
The standard GO (€1,143 excl. VAT) tops out at 2.4 kbps — the speed of a 1990s analog modem. Sufficient for: short text emails, compressed weather GRIBs (XGate, PredictWind), SMS, voice via app. Insufficient for: large attachments, normal web browsing, video calls. The Exec GO (€2,106 excl. VAT) runs on Certus 100 (88 kbps DL) = real email with attachments, light web, HD voice. The Certus plan is ~2× pricier (~€150/month) but offers incomparably better comfort. Workshop recommendation: if you stay at sea 6+ months = Exec GO, otherwise standard GO.
For seasonal use (transatlantic race + 3 months of cruising then boat ashore): prepay. You load 200 or 500 minutes, which roll over. No inactive monthly subscription. For continuous use (world cruise, professional charter): postpay with an included monthly plan, more economical beyond ~50 minutes/month. Skysat distributes both models — we calculate your break-even point when purchasing the terminal.
Skysat does not distribute the Starlink terminal (not part of our current product range — we remain focused on mature LEO + GEO sat solutions with professional SLA such as Iridium). However, we supply and install the deck integration kit: waterproof pass-through Scanstrut DS30 or DS16 depending on cable diameter, high-quality extension cables (8 m or 30 m), 12 V → AC or marine PoE converter for clean power supply. See Starlink installation collection.
Skysat has distributed Iridium and Garmin (inReach) since 2018. Comparator based on 200+ marine satellite installations from 2020–2026, including solo regattas, offshore cruising, transatlantic races, and round-the-world voyages. 2026 indicative distributor prices in France — operator subscriptions not included, rates vary by provider (Iridium direct, MSat Communications, Skytrac, etc.). Starlink Mini Marine listed as a technical reference — Skysat does not distribute the terminal but offers the Scanstrut installation kit.
