Skylo

Skylo is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Skylo rather than just read about it.

Key takeaways

Skylo belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Skylo to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Skylo from memory before moving on to harder problems.

Reference excerpt

Skylo is a satellite communications company headquartered in Mountain View, California that provides connectivity based on 3GPP Rel-17 for SMS, sensor data, and other low-bandwidth services, with plans that include voice calls and limited data for consumer devices. It connects regular cellular devices to satellites through existing satellite networks so they can work when terrestrial cellular coverage is not available, using a system that works with satellite operators, mobile networks, and device makers.

History Skylo was founded in 2017 by a team from Stanford University's space lab. The company first focused on satellite connectivity for IoT devices, then moved into direct-to-device satellite services for smartphones after satellite messaging appeared on consumer phones in the early 2020s. Skylo built its system around NB-IoT and later 3GPP Release 17 standards for phone-to-satellite communications, and its network and support systems were deployed around that technology. By 2024, Skylo said its systems had already handled more than one million satellite-based messages. In 2024, Skylo raised US$37 million in funding from Intel Capital and Innovation Endeavors, with participation from venture funds linked to BMW and Samsung. In 2025, Skylo announced another US$30 million funding round led by NGP Capital and said it had expanded commercial service to the United States, Brazil, Australia, and New Zealand.

Services Skylo provides direct-to-device satellite connectivity that allows compatible smartphones and IoT devices to send and receive SMS when cellular coverage is not available, using 3GPP Release 17 non-terrestrial network standards. In a trial in Greece, Skylo's satellite network was integrated into Cosmote's mobile network to enable SMS over a geostationary satellite using a device powered by the Snapdragon X80 modem-RF system. On consumer smartphones, Skylo's service has been available on Pixel 9 phones and Verizon Galaxy S25 models, starting with emergency satellite messaging and expanding to everyday SMS text messaging. Voice calls and a limited amount of data are expected to be rolled out for consumer devices. For wearables, Skylo's direct-to-device satellite connectivity for smartwatches was named a CES Innovation Awards honoree in 2026. Skylo's network has powered Satellite SOS on select smartphones since August 2024 and Satellite SMS since March 2025, and in August 2025 a smartwatch with built-in satellite communications powered by Skylo was introduced with the Google Pixel Watch 4.

Worked examples

Example 1 — a first encounter with Skylo

Start with the simplest possible case. Write down what Skylo claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Skylo before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Skylo ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Skylo

In research: Skylo appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Skylo in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Skylo is common in secondary-school and first-year university syllabi. It links to neighbouring topics American companies established in 2017, Communications satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Skylo outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Skylo in simple terms?

Why does Skylo matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Skylo?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
