What satellite has the highest resolution?
GeoEye-1 satellite
The GeoEye-1 satellite has the high resolution imaging system and is able to collect images with a ground resolution of 0.41 meters (16 inches) in the panchromatic or black and white mode. It collects multispectral or color imagery at 1.65-meter resolution or about 64 inches.
Which country has highest resolution satellite?
China launched the Gaofen-7 imaging satellite in November, and the country has just shared the first of its high-resolution, 3D shots. The satellite is sensitive enough to height that it should be able to spot a single person from 500 kilometers up.
What resolution do satellites have?
Since satellites orbit 500km above the earth at a speed of more than 20,000km/h, the positioning device needs to be very sophisticated to be accurate….Accuracy.
| Satellite | Resolution | Accuracy |
|---|---|---|
| #1 | 0.31 m | < 5.0 m |
| #2 | 0.41 m | 3.0 m |
| #3 | 0.55 m | 23 m |
| #4 | 0.82 m | 9 m |
Which imagery has the highest resolution data?
1. Google Earth – Free access to high resolution imagery (satellite and aerial) Google Earth offers free access to some of the highest resolution satellite imagery, although the highest resolution images are actually taken from airplanes. Most of the data on Google Earth was taken in the last 3-4 years.
How close can satellites zoom?
The newest US spy satellites, meanwhile, can distinguish objects less than 10 centimeters across, the BBC reports. This is less than the length of some smartphones and sharp enough to zoom in on someone’s head. (Although images of either would appear blobby at that resolution.)
What is the best satellite imagery?
8 Top Free Satellite Imagery Sources
- NASA Worldview. The app is designed for interactive viewing of satellite images by EOSDIS NASA.
- Zoom Earth.
- Google Earth.
- USGS Earth Explorer.
- DigitalGlobe Open Data Program.

- Sentinel Hub.
What is the most advanced satellite?
Landsat 9 Launch Time As Most Advanced Satellite to Study Earth Heads Into Orbit. Landsat 9, the newest and most powerful Earth-observing satellite, is set to launch on Monday.
What does 50cm resolution mean?
In remote sensing, spatial resolution refers to the size of the smallest possible feature that can be displayed in a satellite image. A satellite with a resolution of 50cm per pixel takes clearer images showing finer details than a 10m per pixel resolution satellite.
What does 30 meter resolution mean?
Spatial resolution of images acquired by satellite sensor systems is usually expressed in meters. For example, we often speak of Landsat as having “30- meter” resolution, which means that two objects, thirty meters long or wide, sitting side by side, can be separated (resolved) on a Landsat image.
How do you find high resolution imagery?
To improve a picture’s resolution, increase its size, then make sure it has the optimal pixel density. The result is a larger image, but it may look less sharp than the original picture. The bigger you make an image, the more you’ll see a difference in sharpness.
How many spy satellites are there?
Globally, there are between 2,500 and 2,800 active satellites, including those used for non-military purposes, such as Earth observation, or massive satellite internet constellations, like SpaceX’s Starlink. Military satellites account for about a fifth of all satellites.
Are there any very high resolution optical satellites?
VERY HIGH RESOLUTION OPTICAL SATELLITES The limit between high and very high resolution optical satellites is not fixed in general, but dominating it is accepted to talk about very high resolution if the sensor has a panchromatic GSD of 1m and better. Table 1 shows the very high resolution satellites available for civilian use.
Who is the provider of high resolution satellite imagery?
Airbus has entered into an agreement with Twenty-First Century Aerospace Technology Co. Ltd (21AT), the Chinese commercial satellite operator, for the distribution of the images acquired by their TripleSat constellation. A new high-resolution sensor offers monitoring of any place on Earth revealing details as small as 80 centimetres.
What is the resolution of a satellite image?
The satellite is equipped with a Multi-Spectral Camera (MSC) working in a strip mode operation to capture defined observation areas one at a time with a swath width of 15 km Nadir. The sensor delivers panchromatic as well as four-band multispectral imagery with a resolution of 1,0 m/pxl.
What kind of satellite imagery does Airbus DS use?
Currently, Airbus DS obtains and offers for both commercial and private use high-resolution satellite imagery from the following satellites: Pléiades 1A and 1B, SPOT 5, 6, 7 among others.
