Tasking Just Got Easier With the TripleSat Constellation

Are you in need of imagery of a particular area as soon as possible?

Or do you need up-to-date imagery of an area that other satellites may have missed, even in historically competitive regions such as China, Nigeria and the Philippines?

If so, TripleSat is the satellite constellation for you!

TripleSat can be tasked to collect imagery of any location on Earth, every single day; and as the name suggests, TripleSat is a constellation of three satellites working in unison to collect high-resolution 1-meter panchromatic and 4-meter (m) multispectral imagery around the world. With the widest swath of any high-resolution system at 23.4 kilometers (km) and with daily revisits, TripleSat is an ideal choice when you need newly collected imagery of a given location.

A Focus on New Image Collection and Tasking

21AT, the owner of the TripleSat constellation, has placed all of their focus on new collections of imagery. This emphasis means that tasking the TripleSat constellation has the shortest timelines available. Traditionally, it may take many months to receive your requested imagery when tasking high-resolutions satellites, and this is especially the case in regions with higher demand and historic cloud cover. TripleSat is able to take daily collections of anywhere, making it the go-to option when seeking new imagery of a specific location. TripleSat imagery is also available to academics at a 20% discount.

The Widest Imagery Footprint Available

The TripleSat constellation features the widest imagery footprint of any high-resolution satellite with a width of at least 23.4-km. This larger width means that fewer scenes are needed for full coverage and thus tasking a large area can be accomplished more quickly. Not only does the TripleSat constellation collect imagery fast, it also looks great! Take a look at the imagery samples in this article taken over Alexandria, Egypt and Dubai, United Arab Emirates.

Key TripleSat Specifications

To familiarize yourself a bit more with TripleSat, here are a few of its key imaging specifications:

  • Launch Date July 10, 2015
  • Spectral Bands panchromatic, 4-band multispectral (blue, green, red, and near-infrared [NIR])
  • Resolution
    • 5° off-nadir – 0.99-m panchromatic & 3.96-m multispectral
    • 25° off-nadir – 1.23-m panchromatic & 4.92-m multispectral
    • 35° off-nadir – 1.58-m panchromatic & 6.32-m multispectral
  • Revisit Time
    • 35° off-nadir or higher – daily
    • 25° off-nadir – 2 days, +/- 0 to 40° latitude; daily, greater +/- 50° latitude
    • 15° off-nadir – 3 days, +/- 0 to 30° latitude; 2 days, +/- 40 to 60° latitude; daily, greater +/- 70° latitude
  • Swath Width 23.4 km (varies with orbital height and off-nadir angle)
  • Orbit Height 651 km; three satellites in same orbital plane exactly 120° apart

When you want to task an area of the world lacking the current coverage you need, TripleSat is a fantastic solution. Fast, flexible and ready to task, this satellite constellation is a definitely worth considering for your next project.
