Indra
Satellite weather for expeditions

Decision-grade weather beyond cell coverage

Indra delivers a full multi-day mountain forecast to a satellite text message — enough to decide whether tomorrow is a summit day, from a place with no bars and a rationed battery.

How it works

You plan the trip before you leave. Indra sends the weather while you are out.

1 · Plan your waypoints

Before the trip, you build a location plan in the Indra web app: named waypoints with coordinates, and the dates you expect to be at each one. Import a GPX route if you have one.

2 · Schedule your forecasts

Each scheduled message is pinned to a date, a waypoint, and a send time in that waypoint's own timezone. You choose how many you want and when — typically one the evening before a big day.

3 · Read it in the field

Forecasts arrive as text messages on your satellite-capable phone. The Indra app decodes each one into a full meteogram, with no data connection required to read it.

What a forecast looks like

One 160-character message carries up to seven days of temperature, wind, gusts, direction, precipitation and freezing level. It looks like this on the wire — the app turns it back into a forecast.

Prefer plain words to a decoded chart? TXT ON switches to readable text. The other field commands are WX (forecast), SUN (sunrise/sunset), FZL (freezing level and winds), and SKED (pause or resume scheduled messages).

About our text messages

Indra is a text-message service. Here is exactly what we send, when, and how to stop it.

How you opt in

You add your phone number to your own Indra account in the web app, and then prove the device is yours by texting a one-time pairing code back to Indra from that phone. Until a device completes that round trip, Indra will not send it anything and will not answer messages from it. We never add a number that has not confirmed itself, and we do not buy, rent, or share phone number lists.

What we send

We do not send marketing, promotions, or anything you did not schedule.

How often

Message frequency varies and is set by you. A typical trip is one to three messages per day while you are in the field, plus one reply for each message you send. Between trips, most accounts receive nothing.

Stopping and getting help

Reply STOP to any message to stop all messages to that number. Reply HELP for help, or email [email protected]. Message and data rates may apply, and carrier or satellite-service charges are set by your carrier, not by Indra.

STOP works, and it is permanent until you re-pair. If you send STOP while you are in the field, your carrier blocks further messages from us to that number — including forecasts you scheduled for later in the trip. We cannot override that from our end. Use SKED OFF instead if you only want to pause scheduled sends.

What Indra is not

Indra is an informational weather service, not a safety service. It is not an emergency or SOS service, it cannot summon help, and nobody is monitoring your messages or your location. Weather forecasts are predictions and are routinely wrong. Satellite message delivery is best-effort and messages can arrive late, out of order, or not at all. Carry an emergency beacon or satellite messenger with SOS, and make your own decisions in the field. See the Terms of Service.
