'GPS 2.0' outline calls for open, hackable, interfaces

If Google and Apple are going to provide location services, why not mash 'em up?


The group that created GPS wants it opened up so it's easier for people to compete on its individual components.

Californian nonprofit The Aerospace Corporation also wants to address the weaknesses that have emerged in GPS in the decades since it was first created – things like jamming and resiliency – without compromising accuracy.

Its so-called “Project Sextant” – outlined in detail in this document (PDF) obtained by Breaking Defense – also notes that while there are many alternative PNT (position, navigation and timing) proposals around, the vertically-integrated nature of GPS makes it hard to adopt them.

For example, there are lots of potential sources of position information that could supplement GPS, for example if the satellite signal is degraded: the world's full of terrain maps, cell towers, Wi-Fi hotspots, individual smartphones, or inertial guidance systems.

In the absence of APIs and interfaces that let this information be plugged into the GPS environment, what happens instead is that others (for example Google and Apple) take the GPS data and try to supplement it with (say) Wi-Fi base station locations.

The paper proposes instead that the individual components of GPS (image below) could be decomposed to allow competing systems to slot into each layer of GPS 2.0.

This would come from the creation of an “open source PNT”, which would “distribute PNT over many devices, technologies and phenomenology” (the latter referring to the phenomena that lies beneath timing, such as atomic clocks).

Another piece of the GPS 2.0 proposal is to give users something analogous to the signal strength indicator they get for mobile signals. That way, the end user can tell (for example) whether a system is operating at degraded accuracy, or even in the presence of a suspected jammer.

Project Sextant's authors say a new, independent body should be put in charge of evaluating and coordinating alternative PNTs for critical applications.

  • Twitter founder Dorsey beats hasty retweet from the board
    As shareholders sue the social network amid Elon Musk's takeover scramble

    Twitter has officially entered the post-Dorsey age: its founder and two-time CEO's board term expired Wednesday, marking the first time the social media company hasn't had him around in some capacity.

    Jack Dorsey announced his resignation as Twitter chief exec in November 2021, and passed the baton to Parag Agrawal while remaining on the board. Now that board term has ended, and Dorsey has stepped down as expected. Agrawal has taken Dorsey's board seat; Salesforce co-CEO Bret Taylor has assumed the role of Twitter's board chair. 

    In his resignation announcement, Dorsey – who co-founded and is CEO of Block (formerly Square) – said having founders leading the companies they created can be severely limiting for an organization and can serve as a single point of failure. "I believe it's critical a company can stand on its own, free of its founder's influence or direction," Dorsey said. He didn't respond to a request for further comment today.

  • Snowflake stock drops as some top customers cut usage
    You might say its valuation is melting away

    IPO darling Snowflake's share price took a beating in an already bearish market for tech stocks after filing weaker than expected financial guidance amid a slowdown in orders from some of its largest customers.

    For its first quarter of fiscal 2023, ended April 30, Snowflake's revenue grew 85 percent year-on-year to $422.4 million. The company made an operating loss of $188.8 million, albeit down from $205.6 million a year ago.

    Although surpassing revenue expectations, the cloud-based data warehousing business saw its valuation tumble 16 percent in extended trading on Wednesday. Its stock price dived from $133 apiece to $117 in after-hours trading, and today is cruising back at $127. That stumble arrived amid a general tech stock sell-off some observers said was overdue.

  • Amazon investors nuke proposed ethics overhaul and say yes to $212m CEO pay
    Workplace safety, labor organizing, sustainability and, um, wage 'fairness' all struck down in vote

    Amazon CEO Andy Jassy's first shareholder meeting was a rousing success for Amazon leadership and Jassy's bank account. But for activist investors intent on making Amazon more open and transparent, it was nothing short of a disaster.

    While actual voting results haven't been released yet, Amazon general counsel David Zapolsky told Reuters that stock owners voted down fifteen shareholder resolutions addressing topics including workplace safety, labor organizing, sustainability, and pay fairness. Amazon's board recommended voting no on all of the proposals.

    Jassy and the board scored additional victories in the form of shareholder approval for board appointments, executive compensation and a 20-for-1 stock split. Jassy's executive compensation package, which is tied to Amazon stock price and mostly delivered as stock awards over a multi-year period, was $212 million in 2021.

  • Confirmed: Broadcom, VMware agree to $61b merger
    Unless anyone out there can make a better offer. Oh, Elon?

    Broadcom has confirmed it intends to acquire VMware in a deal that looks set to be worth $61 billion, if it goes ahead: the agreement provides for a “go-shop” provision under which the virtualization giant may solicit alternative offers.

    Rumors of the proposed merger emerged earlier this week, amid much speculation, but neither of the companies was prepared to comment on the deal before today, when it was disclosed that the boards of directors of both organizations have unanimously approved the agreement.

    Michael Dell and Silver Lake investors, which own just over half of the outstanding shares in VMware between both, have apparently signed support agreements to vote in favor of the transaction, so long as the VMware board continues to recommend the proposed transaction with chip designer Broadcom.

  • Perl Steering Council lays out a backwards compatible future for Perl 7
    Sensibly written code only, please. Plus: what all those 'heated discussions' were about

    The much-anticipated Perl 7 continues to twinkle in the distance although the final release of 5.36.0 is "just around the corner", according to the Perl Steering Council.

    Well into its fourth decade, the fortunes of Perl have ebbed and flowed over the years. Things came to a head last year, with the departure of former "pumpking" Sawyer X, following what he described as community "hostility."

    Part of the issue stemmed from the planned version 7 release, a key element of which, according to a post by the steering council "was to significantly reduce the boilerplate needed at the top of your code, by enabling a lot of widely used modules / pragmas."
