ARGOS 위성 트랜시버 쉴드 -ARTIC R2
(ARGOS Satellite Transceiver Shield - ARTIC R2)
개요
- 본 제품은 ARGOS 위성 트랜시버 쉴드 -ARTIC R2 입니다.
- ARGOS 위성 네트워크를 이용하여 짧은 데이터를 주고 받을 수 있게 하여 주는 제품으로 극지방을 포함한 지구 어디서든 사용이 가능합니다.
- ARGOS 2,3,4 통신을 위해 테스트된 트랜시버로 낮은 전류 소비를 하며, 간단하게 동작합니다.
- 안테나도 매우 가벼운 형태의 quarter-wave 와이어 안테나를 사용합니다.

- Our transceiver shield has been tested and certified by Kinéis for ARGOS 2, 3 and 4 communication. Compared to other satellite communication systems, our shield has a much lower current draw and will work with a very simple, very lightweight quarter-wave wire antenna. The ARTIC R2 chipset on our shield operates from 3.3V and the on-board flash memory enables fast boot times. If you don't need the full transmit power, or want to conserve your battery life, you can transmit at reduced power too thanks to the opto-isolated gain pin. Our shield is designed to be used with our SparkFun Thing Plus - Artemis but will work with any of our Thing Plus boards. Want to solder on header pins so you can attach hook-up wires or plug it into a breadboard? You can do that too. The interface is 3.3V SPI and will work with a huge range of microcontrollers.

Our Arduino Library makes it really easy to get up and running with ARGOS. We've provided a full set of examples which will let you: configure the ARTIC R2 chipset; predict the next satellite pass; receive allcast and individually-coded messages; transmit messages using ARGOS 2, 3 and 4 encoding.
The ARGOS satellite system is restricted to specific programs and applications. Please check that your project meets these requirements before buying hardware. CLS (France) and the Woods Hole Group (America) will be able to advise if your project meets the requirements. "To meet system use requirements, all programs using Argos have to be related in some way or other to environmental protection, awareness or study, or to protecting human life."
