In order to support analysis and monitoring using
Japanese Earth Observation satellite
PASCO starts offering package purchase of ALOS-2 satellite data sets,“InSAR Package”
PASCO CORPORATION (Headquarters: Tokyo, Japan; President and CEO, Dr. Hideki
Shimamura, hereinafter referred to as PASCO) distributes data and images acquired by ALOS –2 (The Advanced Land Observing Satellite 2: Daichi-2) satellite which is owned by the Japan
Aerospace Exploration Agency (hereinafter referred to as JAXA), according to the agreement withJAXA with its distributors.
As one of the new sales items, PASCO will start selling a new service "InSAR Package" (hereafterthe Service).
In the recent years, natural disasters have occurred more frequently around the world, andresearches for disaster prevention have been actively implemented. In particular, research using
earth observation satellites is gaining attention as an effective method because a wide range ofinformation can be obtained on a regular basis. Among them, the Synthetic Aperture Radar (SAR)
satellite represented by ALOS-2 is effective for periodic observation because images are suitable
day and night regardless of atmospheric weather conditions. Interferometric SAR analysis (InSARanalysis) is suitable for land subsidence and deformation associated with a natural disaster
observation, and its needs are increasing year by year.
In order to respond to such needs, this service will be provided as a package fee basis, so that theusers, who conduct InSAR analysis multiple times in a certain period and/or long-term monitoring
periods, can purchase the data sets as a “Package Purchase”.
■ About InSAR analysis
It is possible to measure the displacement of the ground surface (how much the ground moved)from the difference of observation data (reflection information) over multi temporal, more than twotimes, observation periods (Fig. 1). Such analysis method is called InSAR analysis. This analysis
method is particularly used in the fields such as ground change monitoring and estimation of urbanchanges. Fig. 2 shows the ground change estimated by InSAR analysis using the observation data
before and after the 2016 Kumamoto earthquake disaster in Japan. It can be confirmed that thefluctuation occurred along the fault from the epicenter.

This service applies a discount price when applying the following conditions to perform
observation (InSAR analysis and monitoring) with the provision of multiple image acquisitions
during certain period of time.
< Applicable condition >Data sets acquired within 1 year from the first acquisition date under the same conditions(observation location / observation mode / polarization / angle) are applicable to InSAR packageprice.( Users shall purchase 5 or more scenes acquired within 6 months from the first acquisition
date.) And, before accepting orders, we will check the possibility of acquisition.(After confirming
the possibility, we will notify you and then you can place an official order.)< Prices of this service >For Reference Only

ALOS-2 is a Japanese Earth Observation Satellite equipped with L-band surface visualization
radar "PALSAR - 2" sensor. PALSAR-2 is a Synthetic Aperture Radar that transmits radio waves
to the ground surface and receives radio waves reflected from the ground surface to obtain
information. Unlike optical sensors, it is capable of observing day and night, and in all weather
conditions. It is widely used in various fields such as disaster situation grasping, environmental
monitoring, land use survey and resource exploration.
< About L-band >The L-band is one of the bands of microwave(frequency: 300 MHz to 3 THz, wavelength:
electromagnetic wave of 0.1 m to 1.0 mm),representing frequency of 1 to 2 GHz andwavelength of 15 to 30 cm. L-band has acharacteristic that radio waves pass throughvegetation and part of it reaches the groundsurface.
Therefore, it is also possible to obtain information on vegetation and the ground surface.
■ Background of PASCO Satellite BusinessIn 2005, PASCO launched a project to provide geospatial information using satellites, and inearnest with the commencement of the operation of TerraSAR-X satellite in December 2007,
PASCO was fully involved in the satellite business. As of September 2018, we have the commercial
right to use 20 Earth Observation satellites operated around the world for our geospatial solutions
services in Japan. Additionally, we provide the solution services globally by utilizing satellites’ datasuch as landslide monitoring in the mountainous areas, ground change monitoring, urban change
analysis, agricultural land management, etc.
