The image of 300 floating objects was taken by the Thaichote satellite on Monday, a day after images from a French satellite purported to show 122 such objects.
The site was about 2,700 kilometres from Perth and about 200 kilometres from the international search area where the flight is thought to have come down. Some objects were more than two-metres long, Anond Snidvongs, executive director of Thailand's Geo Informatics and Space Technology Development Agency, said.
The missing Malaysia Airlines Flight MH370 with 239 people on board, including five Indians, crashed in remote southern Indian Ocean with no survivors and their families have been informed, Malaysia had announced on Monday.
After 19 days of searches, there have been multiple sightings of possible debris, but no wreckage has been retrieved. The flight took off from Kuala Lumpur on March 8 and veered southward into the Indian Ocean for unknown reasons.
The images of 300 floating objects have already been submitted to the Thai government and were relayed to Malaysian authorities yesterday, officials said.
Thaichote or Thailand Earth Observation Satellite is a remote sensing satellite for natural resources observation.
Earlier, Australian and Chinese satellites had also detected unidentified debris.
The Australian Maritime Safety Authority (AMSA) today called off the air search because of thunderstorms and gale-force winds. Ships will try to continue the search, Australian officials said.
AMSA tweeted: "Update: Ships staying in search area & will attempt to continue searching but all planes returning. Bad weather expected for next 24 hours."
