  Satellite Internet of Things (Sat-IoT) is a novel framework in which
satellites integrate sensing, communication and computing capabilities to carry
out task-oriented communications. In this paper we propose to use the Long
Range (LoRa) modulation for the purpose of estimation in a Sat-IoT scenario.
Then we realize that the collisions generated by LoRa can be harnessed in an
Over-the-Air Computing (AirComp) framework. Specifically, we propose to use
LoRa for Type-based Multiple Access (TBMA), a semantic-aware scheme in which
communication resources are assigned to different parameters, not users. Our
experimental results show that LoRa-TBMA is suitable as a massive access
scheme, provides large gains in terms of mean squared error (MSE) and saves
scarce satellite communication resources (i.e., power, latency and bandwidth)
with respect to orthogonal multiple access schemes. We also analyze the
satellite scenarios that could take advantage of the LoRa-TBMA scheme. In
summary, that angular modulations, which are very useful in satellite
communications, can also benefit from AirComp.
