Q. Consider the following comparisons between Resourcesat-1 and Resourcesat-2:

1. Resourcesat-2 is able to collect data from a wider strip of the Earth's surface than Resourcesat-1.
2. Resourcesat-2 provides remote sensing data services for the entire globe, while Resourcesat-1 covered only selected areas.
3. Resourcesat-2 was launched with an additional payload known as AIS (Automatic Identification System) from COMDEV, Canada, for experimental ship surveillance in the VHF band.

Which of the above statements is / are correct?
Answer: 1 and 3 are correct
Notes: Statement 1 is correct as Resourcesat-2 features enhanced swath width compared to Resourcesat-1, collecting data from a wider strip of land. Statement 2 is incorrect; Resourcesat-2 extended, but did not uniquely provide global remote sensing coverage. Statement 3 is correct: it carried an experimental AIS payload for ship surveillance in VHF band, highlighting an additional capability over its predecessor.
