Lacuna Space 发射具有 LoRaWAN 的卫星

Written by Remi Lorrain | 09 September 2019

Semtech’s LoRa® devices and the LoRaWAN® protocol offer several advantages for the Internet of Things (IoT) that have enabled it to lead in a competitive marketplace. Perhaps the most important of these advantages is LoRa devices’ unique capacity for long-range data communication. A single LoRa-based gateway provides deep indoor connectivity in underground or city environments, and connectivity to LoRa-enabled end nodes from up to 30 miles away in rural environments. This is especially important in parts of the world where Cellular connectivity is scarce or nonexistent. In places such as these, LoRaWAN-based networking and LoRa-enabled end nodes provide the quickest to deploy and most cost-efficient option for IoT connectivity, enabling smarter solutions that could not otherwise exist.

尽管如此,世界上仍有一些地区由于地理偏远和/或特殊的环境特征,难以经济高效地部署任何地面物联网网络(甚至支持耗电传感器),例如在北极的最北端或撒哈拉沙漠深处。到现在为止,这要感谢 Lacuna Space 的工作。他们是一家物联网解决方案和小型卫星技术的创新提供商,计划通过卫星为地球上任何地方的传感器提供基于 LoRaWAN 的覆盖,并于近期结束了第一阶段的测试。

Providing Out-of-this-World Connectivity

Lacuna Space 位于英国,是一家连接解决方案提供商,使物联网解决方案提供商能够为传感器和移动设备提供简单可靠的数据连接。Lacuna 的目标是实现无缝的全球覆盖,避免在不同的地面网络间漫游的复杂性、成本和功率要求。利用 LoRaWAN 的低功耗特性,Lacuna 使客户能够连接传感器,用单个电池进行长达五年的通信。无论传感器位于何处,它们都可以提供广泛服务的能力:如资产追踪和监测,乃至智能能源管理和智能农业。天空才是极限。

着眼于未来,Lacuna 正在为客户的互操作性、灵活性以及最重要的速度要求提供支持。在一月份于阿姆斯特丹举行的 The Things Conference 上,Lacuna 宣布组建一个基于 LoRa 的太空网络。这是一个非营利性的基金会,Lacuna Space 将借此支持其他卫星运营商运行其支持 LoRa 的卫星网关,并利用彼此的卫星基础设施来实现全球覆盖。所有消息都经过加密,虽然由一颗卫星负责检测,但发送给另一家运营商的消息会被无缝中继。Lacuna 表示,该系统的工作方式“有点像在手机上漫游,但是网关漫游而不是用户漫游。”

We Have Liftoff: Putting a LoRa-based Gateway into Orbit

在过去两年中,Lacuna 一直与 Semtech 合作,以帮助实现其目标,向全球各个角落提供基于 LoRaWAN 的连接。2019 年 4 月 1 日,Lacuna 在印度的 Satish Dhawan 航天中心发射了第一颗卫星,将它与 EMISAT 和其他 27 颗卫星一起带入近地轨道。目前,Lacuna 基于 LoRa 的太空网关位于 6U CubeSat 卫星上,其中几颗由 Nano Avionics 提供。Lacuna 很高兴地宣布,卫星和太空网关在初始调试阶段的表现超出了预期。

According to Thomas Telkamp, Lacuna CTO, test sensors deployed in countries ranging from South Africa, the Netherlands, U.K., Slovenia, U.S., India, Japan, and even remote Reunion Island in the Indian Ocean, were able to communicate effectively with the space gateways. A further three LoRa-equipped satellites launched in the fourth quarter of the 2019 fiscal year, with another set to join the “Lacuna Constellation” before this year’s end, enhancing the overall performance of the network. Importantly, this includes Lacuna’s novel adaptive radio system, which enables signal detection from even the most remote sensors. Finally, Lacuna aims to perform extensive demonstrations of the network toward the end of the year, thanks in part to funding and support from the European Space Agency and U.K. Space Agency.

太空曾被称为最后的前沿,现在则换成了物联网。Lacuna 让一切变得不同,我们迫不及待地想看看接下来会发生什么……

基于 LoRaWAN 的网络促进了连接器件的互操作性,有助于加速物联网革命。无论是公共、共享、私有还是以企业为中心,这些网络都使全球系统集成商能够自由创新。想要了解更多关于 Lacuna Space 等网络提供商的信息?在 Semtech 网站上探索大量基于 LoRaWAN 的网络提供商
