02 / Beyond the local mesh
Keep your mesh.
Add a way beyond it.
Start a message in the MeshSat app, or on your team's local mesh. The gateway provides the satellite link. Explore both paths and the current Android and iOS support below.
App-led message journey / illustrative01 / 03
The complete MSC-2 satellite exchange is still ahead. Android's node-connected 9704 path and standalone mesh-to-modem routing have bench evidence. These diagrams explain the intended workflow. Active airtime, usable radio links and the relevant routing setup are required; message delivery is not guaranteed.
03 / The MeshSat apps
The controls.
The conversation.
The next pass.
Your phone gives you a place to write, follow message status and see predicted satellite passes. The satellite hardware stays in the node.
- Connect your nodePair over Bluetooth and see the connection state.
- Follow each messageDistinguish waiting, sent and failed. Sent does not mean read.
- Plan around the skyView predicted passes. A prediction is not a delivery guarantee.
Actual Android documentation screens. Example readings from earlier development, not a live MSC-2 connection or an iOS screenshot.
iOS
PrototypeThe documented satellite tests use the earlier 9603 node. MSC-2 / 9704 support still needs confirmation. Check release status before planning an iPhone setup.
Support checked 11 October 2026. The Google Play edition has no SMS feature. Do not assume iOS continues relaying after the app leaves the foreground. See platform limits.
04 / The value of sharing
Share the gateway.
Split the hardware cost.
One gateway has one hardware price. See what that means when your team shares it.
The same gateway. A smaller share.

The chart above always shows the gateway hardware alone. Add the other costs here.
The gateway's own radio is included. Start at zero if everyone already has a compatible radio.
Include applicable tax. No retailer price is assumed.

How the calculation works
Every input is visible
MSC-2 hardware = €1.800 + additional radios x your entered unit price. Another setup uses the whole-team hardware quote you enter.
In 24-month mode, each side adds its entered total for service and other required costs. Missing costs are not treated as zero. Enter zero only when you have checked that no such cost applies.
Use the same currency, tax treatment, team size, period and expected usage. Include required fees and contractual commitments. Values are shown to the cent.
Read the result in context
A difference between entered subtotals is not a verified market saving. It does not establish equivalent coverage, reliability, traffic allowance, app support or emergency service.
MSC-2 is a prototype. It shares one gateway, which depends on power, mesh reachability and a usable satellite link. Its first complete-unit satellite exchange is still pending.
No monitored rescue service is included. The red button is intended for a preset quick message.
Plan the shared system
One gateway is a dependency.
Consider where it travels, who can reach it over the mesh, and how the team will operate if it loses power or a link. Choose a setup based on the work it must do.
Research another option
Considering ACR Bivy Stick MESH?
Check the manufacturer's current product and regional plan terms. Its product page describes monitored SOS; MSC-2 has no monitored rescue service. No Bivy price or required subscription count is assumed here.
ACR and Bivy product names identify the referenced third-party product. MeshSat is not affiliated with or endorsed by ACR or Bivy. Product information checked 11 October 2026.
05 / Inside MSC-2
Two radios.
One shared gateway.
Real components, clearly identified. The LILYGO board handles the local mesh. The RockBLOCK modem provides the satellite side of the design.

06 / Built in the open
Know what's proven.
Know what's next.
MSC-2 is a prototype. Here is the current evidence, with the next milestones kept just as visible.
Open the dated test recordMesh to modem
The RockBLOCK 9704 answered, registered and accepted a text. Mesh routing into the modem also worked without a phone.
The first MSC-2 satellite test
Sending and receiving through satellite from the complete pilot unit. This has not yet been demonstrated.
Range. Runtime. Weather.
Real measurements on the pilot unit. No battery-life figure, radio-range promise or water-resistance rating yet.
Read all six test entries
| Item | Status and evidence |
|---|---|
| RockBLOCK 9704 communication | Bench tested, 8 October: answered, registered and accepted a text. |
| Mesh routing without a phone | Bench tested, 8 October: message routed into the modem. |
| Complete MSC-2 satellite exchange | Next test. Not yet demonstrated from the complete unit. |
| Earlier RockBLOCK 9603 node | Sent and received satellite messages from a garden on 27 September. Different hardware; not proof for MSC-2. |
| MSC-2 radio range and battery life | Planned measurements on the pilot unit. |
| Enclosure water resistance | Planned testing. No rating claimed. |

Can I buy one now?
Pre-orders are not open yet. Join the launch list and confirm your e-mail address to receive the opening alert. Signing up does not place an order or reserve a unit.
Does the price include satellite service?
No. The planned launch price covers the hardware package. Satellite airtime is purchased separately from Ground Control. Access fees and usage depend on the plan you choose.
Will it work with my Meshtastic radio?
The design is for compatible radios on the configured mesh, using matching radio and channel settings. It does not automatically bridge every radio within range.
Can I use the Android or iOS app?
The apps provide Bluetooth setup and a messaging interface for supported nodes. Android has a documented 9704 bench path. The iOS satellite evidence uses the earlier 9603 node; it does not establish MSC-2 compatibility. See current platform support.
Can it operate without a phone?
Yes, the design includes a standalone path for configured mesh messages. That mesh-to-modem route has bench evidence. App-led messaging uses a paired phone; the complete MSC-2 satellite exchange still needs its first test.
Is it waterproof?
The enclosure has an O-ring design, but no tested water-resistance rating is claimed. Testing is planned for the pilot unit.
How long does the battery last?
Battery life has not been measured on the complete pilot unit. A figure will be published after testing.
Is it an emergency beacon?
No. MSC-2 is a prototype and is not an emergency service or distress device. The red quick-message button is not monitored, and no rescue service is included.
One shared connection, in development.
