Spire Global Successfully Launches 11 Satellites on SpaceX’s Transporter-15 Mission

Key Terms

radio occultation technical

Radio occultation is a technique that uses a signal from a satellite or spacecraft as it passes behind Earth to sense how the planet’s atmosphere bends and slows that signal, like watching how a flashlight beam dims and blurs when it shines through fog. The measured changes reveal temperature, humidity and ionospheric conditions with high precision, which investors care about because better weather, climate and positioning data improve forecasting, supply-chain planning, agricultural yields and insurance risk models.

automatic identification system technical

An automatic identification system is a radio-based tracking network that lets ships and other vessels share live details about their location, speed, heading and identity so nearby craft and shore stations can see who is where. For investors, AIS works like a live GPS traffic map for the maritime world: it reveals fleet movements, port congestion, cargo flows and unexpected route or idle-time patterns that can signal revenue changes, operational problems or shifting market demand before formal reports arrive.

iot technical

The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.

radio frequency geolocation technical

Radio frequency geolocation uses the characteristics of radio signals—such as timing, signal strength and direction—to determine the physical location of a transmitter or device. Think of it like finding someone by listening to where their voice is loudest or which direction it comes from; it lets businesses and regulators track assets, manage networks, ensure safety and enforce rules. Investors care because it enables services and products (tracking, logistics, network planning, security) that can drive revenue, reduce risk and affect regulatory exposure.

The Spire-built satellites will serve missions focused on advanced environmental monitoring, connectivity and data resilience

VANDENBERG SPACE FORCE BASE, Calif.--(BUSINESS WIRE)-- Spire Global, Inc. (NYSE: SPIR) (“Spire” or “the Company”), a leading global provider of space-based data, analytics and space services, successfully launched eleven satellites aboard SpaceX’s Transporter-15 mission from Vandenberg Space Force Base. The launch included satellites for Spire’s Space Services customers, along with three replenishment satellites that strengthen the Company’s fully deployed, dual-use constellation.

Expanding Customer Missions in Space

On this launch, Spire Space Services deployed satellites for GHGSat and Lacuna Space:

• GHGSat: Spire launched two satellites for GHGSat carrying payloads to monitor greenhouse gas emissions, expanding GHGSat’s constellation dedicated to high-resolution methane detection. Both satellites are equipped with methane detection payloads that enhance the company’s ability to deliver frequent, independent, and precise emissions data from space. Spire has designed and now operates a total of five satellites for GHGSat, supporting its goal of providing actionable insights that help industries and governments track and reduce greenhouse gas emissions.
• Lacuna Space: Spire also launched four satellites for Lacuna Space, each combining a Spire-built platform with Lacuna’s latest-generation IoT payloads. The satellites expand Lacuna’s global constellation designed to deliver low-cost, reliable connectivity to sensors and mobile equipment in remote or underserved regions. The mission supports IoT applications across agriculture, logistics, energy, environmental monitoring, and the blue economy—enabling use cases from improving crop yields to tracking critical assets worldwide.

Spire Strengthens its Dual-Use Constellation

As part of the mission, Spire also launched three satellites carrying advanced Radio Occultation (RO) and Automatic Identification System (AIS) payloads to deliver high-quality atmospheric and radio-frequency data for global weather, climate, and commercial intelligence.

Earlier this month, the Company also launched an innovative radio frequency geolocation (RFGL) satellite co-founded via LuxImpulse programme, which is managed by the Luxembourg Space Agency and implemented by the European Space Agency. The mission launched aboard SpaceX’s Bandwagon-4.
