Multi-axis motion solutions for Aerospace Applications, new from PI

AUBURN, Mass., Aug. 20, 2024 /PRNewswire-PRWeb/ — The number of active satellites in space keeps growing at an accelerated pace. In July, Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics estimated that there are more than 10,000 active satellites orbiting our planet, already. Different estimations expect that number to grow by several 10,000s possible up to 100,000 by the end of the decade.

With the advent of compact CubeSats and commercial spaceflight, the cost of building and transporting a satellite into space has dropped significantly, which has made feasible the use of a global network of low earth orbit (LEO) satellites for free space optical communication via laser beams.

This emerging technology has a huge potential for rapid growth and the increased demand for satellites also drives the need to new test equipment. Commercial and academic institutions developing these satellites continuously work on improved test systems and methodologies to fully validate their hardware before launch.

PI’s 3-DOF spherical air bearing systems are commonly used to test the attitude control systems of small satellites. The frictionless nature of the spherical air bearing makes it easy to simulate a zero-gravity environment, allowing the satellite’s pitch, roll, and yaw control systems to function as they would in space without cumbersome and expensive test simulations, such as traditional drop testing.

PI’s A-651 – A-657 series of spherical air bearings offer frictionless motion in three rotary degrees of freedom – with unrestrained rotation about the vertical Z-axis and +/-45° tilt motion about the horizontal X and Y axes. They are available with diameters from 50mm to 300mm and can carry payloads from less than 20lbs up to 1,400lbs with compressed air at 80 psi.

This variety in size provides solutions for nearly any small satellite, from 1U picosatellites to half-ton minisatellites. The moving element of the PIglide HB spherical air bearing is lightweight to reduce moving mass and moment of inertia, ensuring the test system closely simulates actual satellite behavior.

What is Attitude Control and Zero-Gravity Simulation Testing?
Attitude Control Testing: Spherical air bearings are extensively used for testing the attitude control systems of satellites. They provide a frictionless environment that allows for the simulation of pitch, roll, and yaw movements, which are essential for assessing how a satellite will orient itself in space.

Zero-Gravity Simulation: These bearings simulate a zero-gravity environment by allowing frictionless motion in three degrees of freedom. This capability is vital for testing how satellites will behave in the weightlessness of space without the need for expensive and complex drop tests or parabolic flights.

Most of the small satellites will be used in free space optical communication, promising affordable high-speed internet at any place on the planet.

In addition to the spherical air bearings, PI also provides other solutions for space applications, such as 6DOF hexapod positioning systems that can be used in the validation of optical terminals, such as the OTVT at the MIT Lincoln Laboratory and fast steering mirrors for free space optical communication in LEO satellites.

eSign.AI Named Sole Electronic Signature Technology Provider for Hong Kong Government’s CorpID Project, Building the Foundation for Digital Signing Infrastructure in Hong Kong

Published

on

By

HONG KONG, May 8, 2026 /PRNewswire/ — As Hong Kong’s Digital Corporate Identity Platform (CorpID) counts down to its phased launch, eSign.AI has been appointed as the sole electronic signature vendor in the project, responsible for delivering core digital signing capabilities including digital signatures, certificate management, and signature verification services. CorpID is led by Nexify, a seasoned government systems integrator, as the prime contractor. The platform is expected to launch in phases starting late 2026, with multiple CorpID-based e-government services going live in mid-2027.

CorpID: Government-Grade Digital Identity Infrastructure for Hong Kong Enterprises

The Digital Corporate Identity Platform (CorpID) is an enterprise-level digital services platform launched by the Hong Kong SAR Government, developed under the oversight of the Digital Policy Office (DPO). It is designed to serve as the business equivalent of “iAM Smart,” providing a unified digital identity foundation for Hong Kong enterprises. CorpID’s core mission is to build an integrated digital government infrastructure — offering unified identity authentication, digital signing, form pre-filling, and e-licence storage — replacing paper-heavy, cumbersome traditional processes and enabling smart city development through seamless data connectivity.

The platform is open to companies incorporated under the Companies Ordinance (Cap. 622) and businesses registered under the Business Registration Ordinance (Cap. 310), including sole proprietorships and partnerships. The DPO requires all enterprise-related e-government services to support CorpID within 18 months of launch, and will continue expanding ecosystem coverage through sandbox initiatives, cross-industry identity standard interoperability, and fully online registration processes.

eSign.AI: The Digital Signing Engine Behind CorpID

eSign.AI is an AI-native electronic signature and contract automation platform built for enterprises worldwide, offering a complete signing framework from simple electronic signatures to the highest-level compliant digital signatures — meeting diverse regulatory requirements across industries and jurisdictions.

On the identity verification front, eSign.AI has completed integration with iAM Smart, enabling individual identity verification through Hong Kong’s citizen digital identity system, and providing legally valid digital certificate services for both enterprises and individuals.

Looking ahead, the eSign.AI SaaS platform will be deeply integrated with CorpID, providing enterprise and individual identity verification for Hong Kong businesses, and supporting both electronic and digital signing that complies with Hong Kong’s Electronic Transactions Ordinance — connecting the full digital contracting lifecycle for government and enterprise alike.

Getting Ahead of the AI Era: From eSignGlobal to eSign.AI

The electronic signature industry is undergoing a structural shift from “tooling” to “intelligence.” Market data underscores this acceleration: the AI-powered contract analysis tools market has grown from USD 3.32 billion in 2025 to USD 4.3 billion in 2026, at a CAGR of 29.6%. Signing is just one node in the contract lifecycle — document generation, workflow orchestration, compliance tracking, and post-execution management are all being transformed by AI, and the industry window is closing fast.

In April 2026, the company officially rebranded from eSignGlobal to eSign.AI, completing its strategic transformation from an e-signature tool provider to an AI-native contract automation platform. As the company’s spokesperson noted, this rebrand is not cosmetic — it is an acknowledgment of where the product actually is. Customers were already using eSign.AI to automate workflows that go far beyond the signature itself.

eSign Automation Skill was launched alongside the rebrand — an AI-powered signing automation framework for enterprise workflows that enables complete contract signing through natural language interaction, with no manual intervention required. Whether it is single-party approval, multi-party sequential signing, or large-scale parallel execution, an AI Agent can orchestrate the entire workflow in a single call. All signature initiations and status queries return structured JSON outputs, directly parseable by leading large language models and intelligent workflow systems.

eSign Automation is now available in the OpenClaw ecosystem and supports integration via Claude MCP, ChatGPT, and other leading AI platforms.

By combining AI automation capabilities with CorpID’s government-grade digital identity infrastructure, eSign.AI delivers a complete solution for Hong Kong enterprises — from identity verification to intelligent signing to full workflow automation.
