The report is for researching the current solution using satellites for some of the disaster monitoring. As the mission design is near real-time mapping, searching for data is mandatory.
As for the data, the team is looking for some reference data that's already used in the mission.
The following are the targets that needs to be taken care of from my side:
## Disaster analysis:
### 1. Earthquakes

https://solidearth.jpl.nasa.gov/gess2.html
mainly focused on geodetic measurement of crustal deformation to predict the possible upcoming earthquakes.
can use: InSAR, camera, GPS system
Personal Experience: Using sentinel 1 & 2 for InSAR and optical data, analysis and calculate/draw the fault. Via fault and the energy theory can one predict possible earthquake in the future.
### 2. Iceberg

Currently there's already iceberg tracking with sentinel 1.
It's a long-term disaster. It's already tracked atm.
### 3. storms

basically the same as weather satellite. It tracks the cloud and analyze it. In order to know the strom, knowing the com
Can use: IR camera, optical camera, Wide-band sensor
## Reference satellite design
### 1. traditional satellite:
For a traditional satellite, the figure is a good reference.
### 2. CubeSat
#### Camera system:
For camera system, there are already lots of solutions.

For example, a 3U satellite with optical sensor:
#### InSAR system
For InSAR system, we can reference from the following

EX: ICEYE-X1(although it's a micro-satellite)
As UAV can bring SAR system, satellites shall be able to get the job done too. The problem will be the resolution, which needs to be calculated.
another example is CIRES system concept. It is trying to build an entire system into cube-sats. Orbit is around 500km height.
