                   Amendment No. 5 to Registration Statement on Form S-1
                   (Registration No. 333-134088)
                   ----------------------------------------------------


Ladies and Gentlemen:

      On behalf of ORBCOMM Inc., a Delaware corporation (the "Company"),
transmitted herewith is Amendment No. 5 ("Amendment No. 5") to the
above-referenced Registration Statement on Form S-1 (Registration No.
333-134088) originally filed on May 12, 2006 (the "Form S-1"), marked to show
changes from Amendment No. 4 to the Registration Statement on Form S-1 filed on
October 13, 2006 ("Amendment No. 4").

      This letter is also in response to the comments of the staff of the
Division of Corporation Finance of the Securities and Exchange Commission (the
"SEC") made in the letter dated October 18, 2006 (the "Comment Letter") from Ms.
Peggy Fisher, Assistant Director of the SEC, to Christian G. Le Brun, General
Counsel of the Company, in connection with Amendment No. 4. Set forth below are
the staff's comments contained in the Comment Letter (in bold face type)
followed by the Company's responses.

      In addition to changes made to address the staff's comments, Amendment No.
5 includes the selling securityholder information, required under Item 507 of
Regulation S-K, that was previously omitted and certain updating information
since Amendment No. 4 was filed.

1.    PLEASE NOTE THAT COMMENTS ON YOUR APPLICATIONS FOR CONFIDENTIAL TREATMENT
      SUBMITTED ON OCTOBER 10 AND OCTOBER 13, 2006 WILL BE SENT IN A SEPARATE
      LETTER AND SHOULD BE RESOLVED PRIOR TO REQUESTING ACCELERATION OF
      EFFECTIVENESS.

      The staff's comment is noted and the Company respectfully requests that
the staff provide the comment letter promptly to enable the Company to resolve
any comments.

SUMMARY CONSOLIDATED FINANCIAL DATA, PAGE 9

2.    WE NOTE YOUR DISCLOSURE IN FOOTNOTE 2 THAT "[T]HE COMPLETION OF THIS
      OFFERING AT THE MID-POINT OF THE ESTIMATED RANGE WOULD NOT REQUIRE ANY
      CONTINGENT PAYMENT TO THE HOLDERS OF SERIES B PREFERRED STOCK." PLEASE
      DISCLOSE IN THIS SECTION THE RANGE OF THE CONTINGENT PAYMENT AMOUNTS THAT
      WOULD BE PAYABLE IF THE IPO PRICE PER SHARE IS BELOW $12.50 WITH THE
      MAXIMUM CONTINGENT PAYMENT, SIMILARLY TO YOUR DISCLOSURES ON PAGES 28 AND
      F-60.

      In response to the staff's comment, the Company has revised footnote 2 on
pages 10 and 37 to include the range of contingent payment amounts that would be
payable if the initial public offering price per share is below $12.50,
including the maximum contingent payment amount, similar to the disclosures
contained on pages 28 and F-60.

NOTE 17.  SUBSEQUENT EVENT

SERIES B PREFERRED STOCK, PAGE F-60

3.    ADVISE US AND DISCLOSE THE IMPACT ON YOUR FINANCIAL STATEMENTS IN THE
      EVENT THAT THE IPO PRICE IS LESS THAN $11.00.

      The Company supplementally advises the staff that the consents of certain
holders of shares of Series B preferred stock would not be effective at a price
per share of less than $11.00 and the Series A and Series B preferred stock
would not automatically convert into shares of common stock upon completion of
the initial public offering at such price. As a result, the Company would not be
able to complete its initial public offering on the terms currently contemplated
at a price per share of less than $11.00. In response to the staff's comment,
the Company has revised Note 17 to reflect this fact.

LEGALITY OPINION

4.    WE ASSUME THE AMENDED CERTIFICATE OF INCORPORATION AND BYLAWS WILL BE
      FILED WITH THE SECRETARY OF STATE OF DELAWARE AND THE OPINION WILL BE
      REFILED AS AN EXHIBIT TO REMOVE THAT CONTINGENCY PRIOR TO THE
      EFFECTIVENESS, PLEASE CONFIRM.

      The Company confirms that the amended certificate of incorporation will be
filed with the Secretary of State of the State of Delaware prior to the
effectiveness of the Form S-1 and the opinion of Chadbourne & Parke LLP will be
refiled to remove the contingency prior to the effectiveness of the Form S-1.
