Satlantis’s GEISAT constellation, comprising the GEISAT‑P and HORACIO satellites, provides high–spatio‑temporal methane (CH₄) observations with simultaneous emitter geolocation. Each satellite simultaneously acquires co‑registered visible and near‑infrared (VNIR) and shortwave infrared (SWIR) imagery, allowing accurate attribution of detected plumes, providing straightforward identification of the emission sources.

In addition to methane detection, the synchronized VNIR–SWIR imagery supports a broad range of Earth observation applications. The constellation’s high revisit frequency and fine spatial resolution offer continuous monitoring of vegetation dynamics and land‑cover change. These measurements benefit a range of science and applications use cases including wildfire monitoring, precision agriculture, and coastal monitoring (e.g., harmful algal bloom detection) and more.

The GEISAT Constellation

Mission Size Category	Micro (< 100 kg): The satellite is 20 centimetres wide and 40 centimetres high, with deployable solar panels and a total mass of 21 kg
Payload/Camera	The instrument is an iSIM 90 VNIR SWIR camera. The iSIM-90 instrument is the lightest and most compact optical payload of the iSIM family, able to provide imagery in the VNIR and SWIR spectral ranges, designed to fit 12U/16U CubeSat platforms, while keeping a high performance-to-mass ratio.  iSIM 90 VNIR SWIR provides 10 spectral bands (1 panchromatic, 4 visible and near infrared, and 5 shortwave infrared), with high resolution: a resolution of 2 m in PAN and VNIR and 7 m in SWIR.
Ground sampling distance (nadir pointing)	PAN 2.0 m VNIR multispectral 2.0 m SWIR multispectral 7.0 m
Acquisition pixel pitch	8, 12, 16 (configurable)
Swath width(nadir pointing)	PAN 13.0 km VNIR multispectral 13.0 km SWIR multispectral 8.3 km
Viewing angles	± 30 degrees for nominal operations ±45 degrees roll for emergency operations
On-board Processing	Preliminary image processing performed onboard up to L1A (raw data cropped with ancillary metadata appended). The processing chain from L1A to level L2 is carried out on-ground.
Satellite Bus & Platform	16U CubeSats with a total mass of 21 kg. Equipped with UHF and S-band communication transceivers, as well as an X-band transmitter. The platform includes a payload controller that interfaces between the payload and the satellite, and GaAs solar panels. Additionally, the platform features a flight computer with ADCS functionality, including a reaction wheel, magnetorquer, and GPS systems.
Main operational acquisition modes offered	They enable on-demand observations, including sporadic acquisitions of areas of interest, as well as systematic revisits of targets over time.
