Recently, the enterprise of Beidou Xingtong and Xinxingtong recently released a new generation of ultra-small full-system multi-frequency and high-precision RTK positioning module UM960, which provides high-fixed rate, high-precision and reliable GNSS positioning data for intelligent robots, deformation monitoring, unmanned aerial vehicles, handheld GIS and other fields.

UM960

The size of the UM960 is 12mm16mm2.6mm, which can bring greater freedom and flexibility to the customer's hardware design. While reducing the difficulty of integration, it can make the terminal product design more integrated and smaller in size, so as to expand to more application scenarios.

Compared with the previous generation of star products, the UM960 cloth plate area has decreased by 84%, and the smaller cloth plate area can also bring cost savings to customers.

The UM960 independently developed by Hexinxingtong supports Beidou, GPS, Galileo, GLONASS and QZSS navigation systems, and the frequency points support BDS B1I/B2I/B3I/B1c/B2a *, GPS L1/L2/L5, Galileo E1/E5b/E5a, GLONASS G1/G2, QZSS L1/L2/L5. The support of multi-frequency points in the whole system enables the UM960 to obtain more available satellites and observations under the same occlusion conditions, improve its data availability under severe occlusion scenarios, improve the fixed rate, and meet the application requirements of various scenarios in different regions.

Thanks to the powerful chip performance of Nabulas IV, the overall performance of UM960 has been significantly improved. The UM960 floating-point computing power has been increased by 5 times, the module computing power has been greatly improved, and the RTK solution time has been greatly shortened; In terms of data output, it supports single point positioning+RTK positioning data 20HZ stable output. In addition, UM960 supports 1408 channels to meet the expansion needs of current and future frequency points.

The UM960 ensures that the power consumption is less than 450mW in the case of small size, which is 75% lower than the previous generation of products, and can better meet the industrial application requirements with strict power consumption requirements. The low power consumption feature of UM960 is conducive to solving the problem of working hours of handheld portable devices and other industrial products. In deformation monitoring and other industries, low power consumption can help customers reduce costs.

UM960 supports independent tracking and acquisition of each frequency point. When a certain frequency point is interfered, other frequency points still work normally to ensure that UM960 module can still locate normally in the interference environment.

The UM960 interference detection function can visually display the intensity of interference signals in the current environment. In the performance UAV industry, the environment can be detected before the flight performance to effectively prevent the occurrence of flight accidents; When mapping the location of CORS stations, it is necessary to confirm whether the environment is clean. The UM960 interference detection function can easily detect whether there is interference in the environment, effectively shorten the initial location time of CORS stations, and save the cost of site selection and station construction.

Based on its excellent performance, UM960 can also solve the application pain point problem of low fixed rate and poor accuracy in severe occlusion scenarios, and provide accurate and reliable positioning data for terminal products.

近日,北斗星通旗下企业和芯星通近期发布了新一代超小尺寸的全系统多频高精度 RTK 定位模组 UM960,面向智能机器人、形变监测、无人机、手持 GIS 等领域,提供高固定率、高精度、高可靠的 GNSS 定位数据。

UM960 的尺寸为 12mm16mm2.6mm,可以给客户硬件设计带来更大的自由度和灵活性,在降低集成难度的同时,让终端产品设计的集成度更高、尺寸更小,以便拓展到更多的应用场景。

与上一代明星产品比较,UM960 的布板面积减少了 84%,更小的布板面积,也可以为客户带来成本的节约。

和芯星通自主开发的 UM960 支持北斗、GPS、Galileo、GLONASS 和 QZSS 导航系统,频点支持 BDS B1I / B2I / B3I / B1c / B2a*、GPS L1 / L2 / L5、Galileo E1 / E5b / E5a、GLONASS G1 / G2、QZSS L1 / L2 / L5。全系统多频点的支持,使得 UM960 在同样遮挡条件下能获得更多可用卫星和观测量,提高其在严重遮挡场景下的数据可用率,提升固定率,满足不同地区的各类场景应用需求。

得益于 NabulasⅣ 强大芯片性能,UM960 整体性能提升显著。UM960 浮点运算能力提升了 5 倍,模组算力得到大幅度提升,极大地缩短了 RTK 解算时间;在数据输出方面,支持单点定位 + RTK 定位数据 20HZ 稳定输出。此外,UM960 支持 1408 个通道,满足现在及未来频点的扩展需要。

UM960 保证小尺寸的情况下,功耗小于 450mW,比上一代产品降低了 75%,可以更好地满足对功耗要求严格的行业应用需求。UM960 的低功耗特性有利于解决手持便携设备等行业产品的工作时长问题,在形变监测等行业,低功耗可帮助客户降低成本。

UM960 支持各频点的独立跟踪和捕获,当某一个频点受到干扰时,其他频点依然正常工作,保证 UM960 模组在干扰环境中仍然正常定位。

UM960 的干扰检测功能,可以形象直观的展现当前环境的干扰信号的强度。在表演无人机行业,飞行表演之前就可以先检测环境是否有干扰,有效地防止飞行事故的发生;在测绘 CORS 建站选址时,必须要确认环境是否干净,UM960 干扰检测功能则可以很方便地检测出环境是否有干扰,有效缩短 CORS 建站初期的选址时间,节约选址建站成本。

基于出色的性能,UM960 还可以解决客户在严重遮挡场景中固定率低、精度差的应用痛点问题,为终端产品提供准确可靠的定位数据。

稳定内核维护者 Greg Kroah-Hartman 确认 Linux 6.1 成为 2022 LTS(长期支持)内核。

Linux 6.1

Linux 6.1 是在 2022 年 12 月释出的,计划维护到 2026 年 12 月,仅比目前的 LTS 版本 Linux 5.15 LTS 多两个月。Linux 特定的 LTS 版本最长维护六年,也就是 Linux 6.1 可以一直维护到 2028 年 12 月,但需要与使用内核的行业参与者协调才能确定。Android 系统是主要的行业参与者,它使用的内核版本通常都比较旧。
Android 13 使用的最新内核版本是 5.15。
