Aluminum Telescope for CubeSat
Connect with Raspberry Pi camera

Features

Facility Our consisutent production systemHigh precision machining and Quality assuance process

The basic optical configuration is the Cassegrain method, with the aim of using a primary
mirror that maximizes the specified area to secure light quantity more efficiently, and totransmit light to a refraction system that removes aberrations with an optimized secondary
mirror. Aiming to simplify the assembly adjustment, the most important simplification of the
optical axis adjustment was achieved by integrally processing the mounting mechanism andthe reflective optical element with aluminum.

Max acceleration during ascent：5G/

Splashdown speed: 15m/s 12V DC power supply andwireless communication available
Payload Processing Steps
1.Flight application submission.
2.Payload interface testing.
3.Mount payload to vehicle and conduct final testingat launch site in Hokkaido, Japan.
4.LaunchCompany’s Mission
The past few years have seen an explosive growth in the small satellite market,without
a carrier to send them up to the orbit. Operators had to purchase a seat on hugerockets, often have to book them years ahead of launch.
High cost, long lead time, and unpredictable trajectory
was the normal.
Capability
ZERO is designed to launch a 100 kg (220 lbs) payload to a 500 km Sun-synchronous orbit.
Suitable for small satellites, it supports a variety of payload attachments for easy integration.

The wait is over.
Our goal is to provide ultra low cost, reliable launchservices using readily available COTS equipment

Payload Flexibility
With a payload bay measuring 1.2 m in diameter, ZERO has the largest payload bay in this classof rockets. We can provide customers with customized fairings to support oversized payloads.

MOMO the Sounding Rocket
Successful reach to the space in May of 2019, we hope to provide up to ten launches in a year
for payload and advertising purposes.

Japan Space Systems
Japan Space Systems is an organization for contributing Japanese space industry
development over 30 years with space system developments, satellite operations,natural resource development by satellite data, and international cooperation.

For Field Survey
No pencils, no notebooks for field survey, because you’ve got FIELDNAUT!
FIELDNAUT is originally developed for collecting and comparing survey data withsatellite and GIS data on your target areas. FIELDNAUT collect your location
information (waypoints) with photos and texts. Those waypoints and tracking record
are saved as GeoJSON format, and you can edit with GIS software easily. Your fieldsurvey data files (one GeoJSON file for location and several JPG for photos forwaypoints) can be shared with your colleagues and friends over SNS and Mail.
For Lifestyle
FIELDNAUT has been developed for field survey originally, but FIELDNAUT makes
your lifestyle bit rich. You can use FEIDLNAUT for walking with dogs, jogging andcycling as daily activities, for traveling, climbing, skiing, camping, fishing as leisure andvacation, and for marketing to find good location for your business.
Explore the Earth
