NTN satellite modems

this page contains tests for non terrestrial network (ntn) satellite modems — modules that provide satellite connectivity blues notecard for skylo (note nbglwx) blues notecard for skylo https //shop blues com/collections/notecard/products/notecard for skylo is an m 2 e key module (30 × 42 mm) that supports ntn nb iot satellite connectivity, terrestrial lte, wi fi, and gnss positioning the module features a built in esim and a sim multiplexer that allows switching between the integrated esim and an external sim card for details see the official datasheet https //dev blues io/datasheets/notecard datasheet/note nbglwx/ the note nbglwx provides satellite connectivity through skylo https //www skylo tech/ current satellite service coverage is available on the skylo coverage map https //www skylo tech/resources/geographical coverage the module is not designed for broadband internet access instead, it is intended for low bandwidth iot applications that exchange small amounts of data over satellite networks at infrequent intervals connecting the module to flipper one the note nbglwx module cannot be installed directly inside flipper one because it uses an m 2 key e connector, while flipper one provides an m 2 key b slot for testing, the module was connected to a notecarrier cx v1 7 https //dev blues io/datasheets/notecarrier datasheet/notecarrier cx v1 7/ board, which was connected to the flipper one gpio port through a protoboard power 5 v supplied by the flipper one gpio port interface notecard aux uart (115200 8n1) in future, we plan to use satellite modems with an m 2 key b connector so they can be installed directly inside flipper one testing ntn connectivity data transmitted from the module over ntn nb iot is received by blues notehub service, where it can be viewed and forwarded to your own backend using the notehub api https //dev blues io/api reference/notehub api/api introduction/ messages received from the module can be viewed in the events section of notehub downlink messages follow the same path in reverse data is sent to notehub, which delivers it to the module over the skylo satellite network the following antennas were used during testing ntn antenna quectel yfca011 https //www quectel com/product/yfca011aa 5g adhesive mount fpc cable dipole embedded antenna/ (120x47 mm) gnss antenna generic 1559 1609 mhz during testing, the module transmitted messages containing sample telemetry two floating point values representing temperature and humidity extended logging was enabled on the ntn module, providing a detailed trace of the communication between the module's mcu and the ntn modem using at commands the trace includes information about the cellular network, satellite connection, and the synchronization process see the complete test log https //cdn flipper net/notecard 2026 07 03t15 00 07 log txt
